Check Digit Verification of cas no

The CAS Registry Mumber 158419-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,4,1 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158419-85:
(8*1)+(7*5)+(6*8)+(5*4)+(4*1)+(3*9)+(2*8)+(1*5)=163
163 % 10 = 3
So 158419-85-3 is a valid CAS Registry Number.

An improved synthesis of the C-linked glucuronide of N-(4-hydroxyphenyl)retinamide.

Walker, Joel R,Alshafie, Galal,Abou-Issa, Hussein,Curley Jr., Robert W

, p. 2447 - 2450 (2007/10/03)

Retinoic acid analogues such as N-(4-hydroxyphenyl)retinamide (4-HPR) are effective chemopreventatives and chemotherapeutics for numerous types of cancer. The C-linked analogue of the O-glucuronide of 4-HPR (4-HPRCG) has been shown to be a more effective agent. The synthetic route to this molecule has been significantly improved by access to a key C-benzyl-glucuronide intermediate through employment of a Suzuki coupling reaction between an exoanomeric methylene sugar and an aryl bromide. Preliminary evidence shows 4-HPRCG has chemotherapeutic activity.
