154780-90-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154780-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,7,8 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 154780-90:
(8*1)+(7*5)+(6*4)+(5*7)+(4*8)+(3*0)+(2*9)+(1*0)=152
152 % 10 = 2
So 154780-90-2 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
