Check Digit Verification of cas no

The CAS Registry Mumber 16862-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,6 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16862-77:
(7*1)+(6*6)+(5*8)+(4*6)+(3*2)+(2*7)+(1*7)=134
134 % 10 = 4
So 16862-77-4 is a valid CAS Registry Number.

Effet de substitution dans les positions 3, 5 et 7 en serie spiropyrannique benzothiazolinique

Kister, Jacky,Pommier, Henri Paul,Metzger, Jacques,Guglielmetti, Robert

, p. 2372 - 2378 (2007/10/02)

Benzothiazolinic spiropyrans substituted in the 3, 5, 6, 7, and 8 positions have been studied.The results obtained show the equivalent role of the 3 and 5 substituted positions during the synthesis of merocyanin type compounds.Non-bonded interactions play
