Check Digit Verification of cas no

The CAS Registry Mumber 271600-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,1,6,0 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 271600-99:
(8*2)+(7*7)+(6*1)+(5*6)+(4*0)+(3*0)+(2*9)+(1*9)=128
128 % 10 = 8
So 271600-99-8 is a valid CAS Registry Number.

2,4-Disubstituted thiazoles by regioselective cross-coupling or bromine-magnesium exchange reactions of 2,4-dibromothiazole

Gross, Stefan,Heuser, Stefan,Ammer, Carolin,Heckmann, Golo,Bach, Thorsten

experimental part, p. 199 - 206 (2011/03/18)

Cross-coupling reactions occur on 2,4-dibromothiazole preferentially at the more electron-deficient 2-position. This fact can be favorably used to prepare 2-substituted 4-bromothiazoles, which serve as precursors for 2,4-disubstituted thiazoles. Protocols
