359882-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 359882-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,9,8,8 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 359882-23:
(8*3)+(7*5)+(6*9)+(5*8)+(4*8)+(3*2)+(2*2)+(1*3)=198
198 % 10 = 8
So 359882-23-8 is a valid CAS Registry Number.

Synthesis of (-)-aphanorphine using aryl radical cyclization.
Tamura,Yanagimachi,Kobayashi,Ishibashi
, p. 2427 - 2429 (2001)
[structure: see text] The synthesis of (-)-aphanorphine was achieved by using Bu(3)SnH-mediated aryl radical cyclization of 1-benzyloxycarbonyl-2-(2-bromo-4-methoxyphenylmethyl)-2-methoxycarbonyl-4-(phenylthiomethylene)pyrrolidine, leading to exclusive fo
