145694-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145694-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,9 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145694-33:
(8*1)+(7*4)+(6*5)+(5*6)+(4*9)+(3*4)+(2*3)+(1*3)=153
153 % 10 = 3
So 145694-33-3 is a valid CAS Registry Number.

Convenient syntheses of optically active β-lactams by enzymatic resolution
Nagai,Shiozawa,Achiwa,Terao
, p. 1933 - 1938 (2007/10/02)
Optically active β-lactams were synthesized by lipase-catalyzed kinetic resolution using the enantioselective hydrolysis of N-acyloxymethyl β- lactams (3) in an organic solvent and the transesterification of N- hydroxymethyl β-lactams (2) with vinyl aceta
