Check Digit Verification of cas no

The CAS Registry Mumber 131699-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,9 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131699-93:
(8*1)+(7*3)+(6*1)+(5*6)+(4*9)+(3*9)+(2*9)+(1*3)=149
149 % 10 = 9
So 131699-93-9 is a valid CAS Registry Number.

RING-CHAIN TAUTOMERISM IN 1,3-THIAZOLIDINES

Fueloep, Ferenc,Mattinen, Jorma,Pihlaja, Kalevi

, p. 6545 - 6552 (1990)

NMR spectroscopy was applied to study ring-chain tautomeric equilibria in several substituted 1,3-thiazolidines.The system highly prefers the ring form and only in the case of 2-(2'-hydroxy-5'-bromophenyl)-1,3-benzothiazoline (2d) 1H and 13C NMR spectra r
