Check Digit Verification of cas no

The CAS Registry Mumber 20715-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,1 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20715-27:
(7*2)+(6*0)+(5*7)+(4*1)+(3*5)+(2*2)+(1*7)=79
79 % 10 = 9
So 20715-27-9 is a valid CAS Registry Number.

Total synthesis of 8-methoxygoniodiol related compounds via chiron approach

Yadav, Jhillu Singh,Madhava Rao, Batta,Sanjeeva Rao, Kodepelly

experimental part, p. 1725 - 1730 (2009/12/24)

The stereoselective synthesis of 8-methoxygoniodiol related compounds was accomplished by using readily available δ-gluconolactone as a chiral source. The stereoselective addition of an aryl Grignard reagent on an aldehyde, stereoselective reduction of a keto group and regioselective opening of a chiral epoxide by ethyl propiolate are the key steps involved in this synthesis.
