158779-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158779-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,7,7 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158779-55:
(8*1)+(7*5)+(6*8)+(5*7)+(4*7)+(3*9)+(2*5)+(1*5)=196
196 % 10 = 6
So 158779-55-6 is a valid CAS Registry Number.

Synthesis of enantiomerically pure juvenile hormone II
Kosugi,Kanno,Uda
, p. 1139 - 1142 (2007/10/02)
An efficient preparative method for the enantiomerically pure juvenile hormone II has been developed by applying the diastereoselective alkylation and carbonyl reduction of an optically pure β-keto sulfoxide as the key steps.
