Check Digit Verification of cas no

The CAS Registry Mumber 271601-00-4 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 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 271601-00:
(8*2)+(7*7)+(6*1)+(5*6)+(4*0)+(3*1)+(2*0)+(1*0)=104
104 % 10 = 4
So 271601-00-4 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
