Check Digit Verification of cas no

The CAS Registry Mumber 1242567-17-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,5,6 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1242567-17:
(9*1)+(8*2)+(7*4)+(6*2)+(5*5)+(4*6)+(3*7)+(2*1)+(1*7)=144
144 % 10 = 4
So 1242567-17-4 is a valid CAS Registry Number.

Balsalazide disodium (Colazide) is an oral prodrug of mesalamine (5-aminosalicylic acid) and possesses anti-inflammatory properties. During the process development for balsalazide disodium, we observed eight impurities, namely des-alanine balsalazide, balsalazide-alanine, balsalazide 3-isomer, decarboxy balsalazide, bis-azo salicylic acid, biphenyl-azo salicylic acid, bis-azo diacid, and bis-azo triacid. The present work describes the synthesis and characterization of these impurities. Copyrigh
