145050-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145050-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,0,5 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145050-22:
(8*1)+(7*4)+(6*5)+(5*0)+(4*5)+(3*0)+(2*2)+(1*2)=92
92 % 10 = 2
So 145050-22-2 is a valid CAS Registry Number.

Synthesis of a highly reactive 1,1-dicyanomethylene-1-dethiacephalosporin
Dunlap,Dezube,Keith,Weigele
, p. 6103 - 6106 (2007/10/02)
Synthesis of the 1,1-dicyanomethylene-1-dethiacephalosporin 1a is described. Substitution of the dicyanomethylene moiety for sulfur at position 1 of the cephem nucleus resulted in a highly reactive β-lactam antibacterial.
