17550-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17550-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,5 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17550-74:
(7*1)+(6*7)+(5*5)+(4*5)+(3*0)+(2*7)+(1*4)=112
112 % 10 = 2
So 17550-74-2 is a valid CAS Registry Number.

Enantioselective synthesis of the tumorigenic anti-diol epoxide metabolites of benzo[a]pyrene
Harvey, Ronald G.
, p. 2737 - 2740 (2007/10/02)
Efficient, highly enantioselective syntheses of (+) and (-)-anti-benzo[a]pyrene diol epoxide (BPDE) from 9,10-dihydrobenzo[a]pyrene are described. Initial epoxidation catalyzed by (salen) Mn(III) complex gives 7,8-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (
