128773-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128773-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,7 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128773-39:
(8*1)+(7*2)+(6*8)+(5*7)+(4*7)+(3*3)+(2*3)+(1*9)=157
157 % 10 = 7
So 128773-39-7 is a valid CAS Registry Number.

CONCERNING THE MECHANISM OF FORMATION OF BILIVERDINS FROM b-BILENES
Awruch, Josefina
, p. 1171 - 1180 (2007/10/02)
The oxidation of 1,19-di-t-butoxycarbonyl-b-bilenes with bromine affords not only a major biliverdin, but also minor biliverdins.Elucidation of their structure revealed that cleavage of the b-bilene chain takes place during the oxidation, followed by dime
