Check Digit Verification of cas no
The CAS Registry Mumber 186610-95-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,6,1 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 186610-95:
(8*1)+(7*8)+(6*6)+(5*6)+(4*1)+(3*0)+(2*9)+(1*5)=157
157 % 10 = 7
So 186610-95-7 is a valid CAS Registry Number.

Conformation and Crystal Structure of Dipyrrinones with Oxindole Components
Boiadjiev, Stefan E.,Lightner, David A.
, p. 489 - 499 (2003)
Pyrrole α-aldehydes (2-formyl-4,5-dimethyl- 1H-pyrrole and 2-formyl-N-methylpyrrole) condense readily at C(3) of indolin-2-ones to give dipyrrinone analogs, such as (3Z)-[(4,5-dimethylpyrrol-2-yl)-methylidenyl]- indolin-2-one and (3E)-[(1-methylpyrrol-2-y
