Check Digit Verification of cas no

The CAS Registry Mumber 27815-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,8,1 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27815-90:
(7*2)+(6*7)+(5*8)+(4*1)+(3*5)+(2*9)+(1*0)=133
133 % 10 = 3
So 27815-90-3 is a valid CAS Registry Number.

ETUDE DE LA PROTONATION DES ANIONS PHOSPHOLYLES. OBTENTION DE DIMERES DE PHOSPHOLES -2H.

Lauzon, Guillaume de,Charrier, Claude,Bonnard, Hubert,Mathey, Francois

, p. 511 - 514 (1982)

The protonation of phospholyl anions yields unstable 1-H-phospholes which spontaneously rearrange through 1,5-proton shifts to give 2-H-phospholes ; in turn these species undergo spontaneous Diels-Alder dimerization leading to P-P bonded dimers.
