Check Digit Verification of cas no

The CAS Registry Mumber 134576-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,7 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134576-22:
(8*1)+(7*3)+(6*4)+(5*5)+(4*7)+(3*6)+(2*2)+(1*2)=130
130 % 10 = 0
So 134576-22-0 is a valid CAS Registry Number.

PHOSPHORYLMETHYLPYRIDINES AND THEIR n-OXIDES: SYNTHESIS AND EQUILIBRIUM CH-ACIDITY

Bodrin, G. V.,Matveeva, A. G.,Terekhova, M. I.,Matrosov, E. I.,Petrov, E. S.,et al.

, p. 810 - 818 (2007/10/02)

Certain phosphorylmethylpyridines and their N-oxides were synthesized, which are of interest as extractants and complex-forming agents.Their equilibrium CH-acidity with reference to 9-phenylfluorene (k+ counterion) was studied by the indicator method in dimethyl sulfoxide.The acidifying action of a series of pyridine groupings was characterized by means of ?C- values.
