16568-56-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16568-56-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,6 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16568-56:
(7*1)+(6*6)+(5*5)+(4*6)+(3*8)+(2*5)+(1*6)=132
132 % 10 = 2
So 16568-56-2 is a valid CAS Registry Number.

BILIRUBIN CHEMISTRY. II. SYNTHESIS OF 3-DEVINYL-3-ETHYLBILIRUBIN AND AN IMPROVED PREPARATION OF MESOBILIRUBIN

Monti, Diego,Speranza, Giovanna,Manitto, Paolo

, p. 367 - 370 (2007/10/02)

3-Devinyl-3-ethylbilirubin (5) can be prepared in satisfactory yield from bilirubin (1) through protection of the C(18) vinyl group (according to a method reported previously) and hydrogenation of the other vinyl group with sodium hypophosphite and Raney-Ni.This reducing system was also found to be very suitable for obtaining mesobilirubin (6) from bilirubin.
