Check Digit Verification of cas no

The CAS Registry Mumber 1914-13-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,1 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1914-13:
(6*1)+(5*9)+(4*1)+(3*4)+(2*1)+(1*3)=72
72 % 10 = 2
So 1914-13-2 is a valid CAS Registry Number.

Toda, Takashi,Tokida, Akihiko,Mukai, Toshio,Suzuki, Yoshizo

, p. 1535 - 1538 (2007/10/02)

Thermolyses of dimethylsulfonium 1-(2,6-diphenyl and 2,3,5,6-tetraphenyl-4H-pyran-4-yl)-2-oxo-2-phenylethylides (1 and 3) caused a novel ylide rearrangement to give dimethylsulfonium 1-benzoyl-6-oxo-2,6-diphenyl and 2,3,5,6-tetraphenyl-2,4-hexadienylides (6 and 7) respectively.The formations of oxy-thio-acetal derivatives (11 and 12) of 4-pyranylidene from 3 and its methylphenylsulfonium analogue (4) by base treatment are also reported.
