Check Digit Verification of cas no

The CAS Registry Mumber 71963-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,6 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71963-69:
(7*7)+(6*1)+(5*9)+(4*6)+(3*3)+(2*6)+(1*9)=154
154 % 10 = 4
So 71963-69-4 is a valid CAS Registry Number.

Process for preparing L-5 - methyl tetrahydrofolinate

-

Paragraph 0050-0051; 0055-0056; 0058-0059; 0061-0062, (2021/11/06)

The invention relates to a preparation process of L-5 - methyl tetrahydrofolic acid, which adopts asymmetric catalytic hydrogenation to convert folic acid into (6S) - tetrahydro folic acid, and has high folic acid conversion rate, and (6S) - tetrahydrofolic acid diastereomeric excess degree. By salt formation and crystallization, the (6S) - tetrahydrofolic acid intermediate with extremely high diastereomeric excess can be easily enriched, and thus the yield and purity of L-5 - methyltetrahydrofolinate finally obtained are high. The catalytic hydrogenation process is very mature in industrial application and convenient to operate. The subsequent methylation and salt formation steps are easy to implement, and the preparation process has high economic value and practical value under the condition that the yield and purity of the product are improved.

Process For The Preparation Of Optically Pure Tetrahydropterins And Derivatives, And Specifically Of Optically Pure Tetrahydrofolic Acid And Derivatives Thereof, By Stereospecific Hydrogenation

-

Page/Page column 19-20, (2009/01/20)

Process for the preparation of tetrahydropterin and tetrahydropterin derivatives by hydrogenating pterin and pterin derivatives with hydrogen in the presence of a hydrogenating catalyst, in which the hydrogenation is carried out in a polar reaction medium and metal complexes that are soluble in the reaction medium are employed as the hydrogenation catalysts. The process is suited to the hydrogenation, particularly asymmetric hydrogenation, of folic acid, folio acid salts, folio acid esters, folio acid ester salts or dihydroforms thereof, with the proviso that in the event of using folic acid, carboxylic acid salts thereof or dihydroforms thereof the reaction medium is aqueous, and in the event of using folic acid esters, folic acid ester salts or dihydroforms thereof the reaction medium is an alcohol. The process opens up straightforward access to achiral and chiral pterin derivatives.

Stable crystalline (6R) -tetrahydrofolic acid

-

, (2008/06/13)

Pure and extremely stable crystalline (6S)- and (6R)-tetrahydrofolic acids, absolutely inert even when exposed to air and elevated temperature without stabilizers being added, are prepared by a crystallization process at a pH of ≧3.5 for the preparation of crystalline (6S)-tetrahydrofolic acid and at a pH of ≧2 for the preparation of crystalline (6R)-tetrahydrofolic acid.
