Check Digit Verification of cas no

The CAS Registry Mumber 77655-10-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,5 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77655-10:
(7*7)+(6*7)+(5*6)+(4*5)+(3*5)+(2*1)+(1*0)=158
158 % 10 = 8
So 77655-10-8 is a valid CAS Registry Number.

Composes sulfures heterocycliques. LXXXIX (1). Reactions des ynamines sur les dithiole-1,2 ones-3 et sur les N-phenylimines et thiones correspondantes

Dibo, Ahamada,Stavaux, Madeleine,Lozac'H, Noel

, p. 530 - 538 (2007/10/02)

This paper compares reactions of ynamines 4 with 1,2-dithiol-3-ones 1, N-phenyl-1,2-dithiol-3-imines 2 and 1,2-dithiole-3-thiones 3.In all cases a (2 + 3) dipolar addition is observed, leading to α-(1,3-oxathiol-2-ylidene) thioketones (or thioaldehydes) 5
