Check Digit Verification of cas no

The CAS Registry Mumber 82343-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,4 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82343-13:
(7*8)+(6*2)+(5*3)+(4*4)+(3*3)+(2*1)+(1*3)=113
113 % 10 = 3
So 82343-13-3 is a valid CAS Registry Number.

PHOTOCYCLIZATION OF METHYL 2-ARYLTHIO- AND 2-ARYLOXY-ACETOACETATES A FACILE SYNTHESIS OF BENZOHETEROCYCLES

Sasaki, Tadashi,Hayakawa, Kenji,Ban, Hiroshi

, p. 85 - 91 (2007/10/02)

A series of methyl 2-arylthio- (2) and 2-aryloxy-acetoacetates (3) have been prepared and their tautomeric equilibria have been examined by 1H NMR spectroscopy.S-substitution at the α-position results in an increase of enol tautomer over 90percent, while
