Check Digit Verification of cas no

The CAS Registry Mumber 77978-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77978-85:
(7*7)+(6*7)+(5*9)+(4*7)+(3*8)+(2*8)+(1*5)=209
209 % 10 = 9
So 77978-85-9 is a valid CAS Registry Number.

Pyrrolinones, IV Pyrrolin-2-ones with Electron Attracting Substituents in the &β-Positions

Dobeneck, Henning von,Brunner, Enno,Bunke, Holger,Metzner, Gerhard,Schmidt, Ruediger,et al.

, p. 410 - 424 (2007/10/02)

The pyrrolinones 3-7, synthesized from maleic acid derivatives and enamines and also their reaction products 8-24 are described.By comparison with the classic-type dipyrromethenes 26, 30 and 31 the dipyrromethenes 27 as well as 25, 28 and 29 are shown to exist as lactams (neo-type dipyrromethenes).In basic solution 27 exhibits a deep blue colour which is unusual for dipyrromethenes.
