1222145-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1222145-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,2,1,4 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1222145-89:
(9*1)+(8*2)+(7*2)+(6*2)+(5*1)+(4*4)+(3*5)+(2*8)+(1*9)=112
112 % 10 = 2
So 1222145-89-2 is a valid CAS Registry Number.

A practical method for O-acylation of N -hydroxythiazole-2(3 H)-thiones
Schur, Christine,Gross, Andreas,Hartung, Jens
experimental part, p. 538 - 542 (2010/06/13)
O-Acylation of 4- and 4,5-substituted N-hydroxythiazole-2(3H)-thiones occurred in solutions of acetone upon treatment with solid K2CO3 and a variety of neat acyl chlorides (primary, secondary, and tertiary alkyl, aryl; 60-87% yield; ～10 g scale).
