Check Digit Verification of cas no

The CAS Registry Mumber 129319-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,1 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129319-11:
(8*1)+(7*2)+(6*9)+(5*3)+(4*1)+(3*9)+(2*1)+(1*1)=125
125 % 10 = 5
So 129319-11-5 is a valid CAS Registry Number.

POLYBROMINATED AROMATIC COMPOUNDS. III. SYNTHESIS OF BROMINE-SUBSTITUTED ANISOLES

Shishkin, V. N.,Tanaseichuk, B. S.,Lapin, K. K.,Ivkina, A. A.,Butin, K. P.

, p. 2357 - 2366 (2007/10/02)

Reliable methods were developed for the synthesis of di-, tri-, and tetrabromoanisoles, and all the possible individual isomers were synthesized.The structures of the isomers were proved by alternative synthesis and spectral methods (PMR, IR).It was shown that the published data are incorrect in a number of cases; either the final product was assigned the incorrect structure, or the published methods led to mixture of the various isomers.
