74513-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74513-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,1 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74513-77:
(7*7)+(6*4)+(5*5)+(4*1)+(3*3)+(2*7)+(1*7)=132
132 % 10 = 2
So 74513-77-2 is a valid CAS Registry Number.

Asymmetric synthesis of (2S)-1-(3,4-dihydroxyphenoxy)-3-(3,′4′- dimethoxyphenoxy) ethylamino-2-propanol hydrochloride (RO363)
Narsaiah, Akkirala Venkat
, p. 1897 - 1901 (2006)
Enantiomerically pure (S)-RO363 was synthesized by using (R,R) Salen Co(III) complex for the resolution of terminal epoxide. The hydrolytic kinetic resolution process was carried out at room temperature in excellent enantioselectivity. The method can be a
