Check Digit Verification of cas no

The CAS Registry Mumber 139308-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,0 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139308-50:
(8*1)+(7*3)+(6*9)+(5*3)+(4*0)+(3*8)+(2*5)+(1*0)=132
132 % 10 = 2
So 139308-50-2 is a valid CAS Registry Number.

Double 1,3-Dipolar Cycloadditions of Meso-ionic Heterocycles to N-Substituted Maleimides

Nan'ya, Seiko,Kurachi, Yoshinori,Butsugan, Yasuo

, p. 1853 - 1855 (2007/10/02)

Double 1,3-dipolar cycloadditions of 2,4-diphenyl-3-methyloxazolium 5-oxide and 3-phenylsydnone to two molecules of N-substituted maleimide afforded one or two isomeric 4,8-iminobenzodipyrrole-1,3,5,7-tetrone derivatives owing to the types of heterocycles as well as N-substituents of maleimides.
