Check Digit Verification of cas no

The CAS Registry Mumber 1372422-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,4,2 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1372422-99:
(9*1)+(8*3)+(7*7)+(6*2)+(5*4)+(4*2)+(3*2)+(2*9)+(1*9)=155
155 % 10 = 5
So 1372422-99-5 is a valid CAS Registry Number.

DBU-catalyzed tandem additions of electron-deficient 1,3-conjugated enynes with 2-aminomalonates: A facile access to highly substituted 2-pyrrolines

Yu, Xiuzhao,Zhou, Guanghua,Zhang, Junliang

supporting information; experimental part, p. 4002 - 4004 (2012/06/04)

An efficient, metal free approach to highly substituted 2-pyrrolines by DBU-catalyzed tandem additions (a formal [3+2] cycloaddition) of electron-deficient 1,3-conjugated enynes and 2-aminomalonates under mild conditions was developed.
