41928-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41928-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,2 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 41928-02:
(7*4)+(6*1)+(5*9)+(4*2)+(3*8)+(2*0)+(1*2)=113
113 % 10 = 3
So 41928-02-3 is a valid CAS Registry Number.

Hydroxylation of yohimbine in superacidic media: One-step access to human metabolites 10 and 11-hydroxyyohimbine
Duflos,Redoules,Fahy,Jacquesy,Jouannetaud
, p. 193 - 195 (2007/10/03)
Two major human metabolites of yohimbine (1), 10- and 11-hydroxyyohimbine (2 and 3), were prepared by direct hydroxylation of 1 under superacidic conditions. In this medium, the four positions of the benzene part of yohimbine were hydroxylated and the cor
