Check Digit Verification of cas no

The CAS Registry Mumber 103312-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,3,1 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103312-33:
(8*1)+(7*0)+(6*3)+(5*3)+(4*1)+(3*2)+(2*3)+(1*3)=60
60 % 10 = 0
So 103312-33-0 is a valid CAS Registry Number.

Solid phase synthesis of aminopropenones and aminopropenoates; efficient and versatile synthons for combinatorial synthesis of heterocycles

Westman, Jacob,Lundin, Ronny

, p. 1025 - 1030 (2003)

Simple and fast solid phase methods for the synthesis of heterocycles will be described. Two different three-step methods are presented. The first method includes esterifications of N-protected glycine derivatives to a solid support (Merrifield resin), formation of aminopropenoates and subsequent reaction with dinucleophiles. The second method includes methylamination of a Merrifield resin, formation of aminopropenones via in-situ formation of an active intermediate in a three-component reaction and finally treatment with dinucleophiles to form heterocycles. These procedures lead not only to the formation of heterocycles but also to simultaneous intramolecular cleavage of the products from the resin giving the product in pure form in the solution. In addition, the use of microwave dielectric heating enhanced the velocity of all reaction steps and was found to be a very efficient complement to the solid phase synthesis.

Studies on cerebral protective agents. II. Novel 4-arylpyrimidine derivatives with anti-anoxic and anti-lipid peroxidation activities.

Kuno,Sugiyama,Katsuta,Sakai,Takasugi

, p. 2423 - 2431 (2007/10/02)

In a search for new cerebral protective agents with anti-anoxic (AA) and anti-lipid peroxidation (ALP) activities, a series of 4-arylpyrimidines, bearing an amino moiety in the C-5 position of the pyrimidine nucleus, was synthesized and tested for AA and
