157730-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157730-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,3 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157730-89:
(8*1)+(7*5)+(6*7)+(5*7)+(4*3)+(3*0)+(2*8)+(1*9)=157
157 % 10 = 7
So 157730-89-7 is a valid CAS Registry Number.

Catalytic enantioselective synthesis of macrolides via asymmetric alkylation
Jones, Graham B.,Huber, Robert S.,Chapman, Brant J.
, p. 1797 - 1809 (1997)
Catalytic enantioselective syntheses of the macrolides (R)-(-) phoracantholide and (R)-(+) lasiodiplodin have been achieved. Stereochemistry was introduced in using an arene chromium tricarbonyl derived catalyst, which mediated the enantioselective additi
