90327-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90327-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,2 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90327-21:
(7*9)+(6*0)+(5*3)+(4*2)+(3*7)+(2*2)+(1*1)=112
112 % 10 = 2
So 90327-21-2 is a valid CAS Registry Number.

, p. 713 - 716 (2007/10/02)
The bicyclomycin skeleton (7,9-dibenzyl-5-methylene-7,9-diaza-2-oxabicyclodecane-8,10-dione) was synthesized from 3,6-dimethoxy-2,5-piperazinedione by 6 steps in a 32percent yield.
