1263472-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263472-76-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,4,7 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1263472-76:
(9*1)+(8*2)+(7*6)+(6*3)+(5*4)+(4*7)+(3*2)+(2*7)+(1*6)=159
159 % 10 = 9
So 1263472-76-9 is a valid CAS Registry Number.

Reactions of transition metal carbonyl anions with 2-(1-bromoalkylidene) thiazolidin-4-ones: Halogenophilic attack or deprotonation
Sazonov,D?ambaski,Shtern,Markovi?,Beletskaya
, p. 29 - 33 (2011)
Bromophilic attack by the transition metal carbonyl anion, [Re(CO) 5]Na (pKa = 21.1), on 2-(1-bromoalkylidene)thiazolidin-4- ones is significantly faster than abstraction of an acidic lactam hydrogen (pKa ～17-18), when the
