Check Digit Verification of cas no

The CAS Registry Mumber 74628-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,2 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74628-11:
(7*7)+(6*4)+(5*6)+(4*2)+(3*8)+(2*1)+(1*1)=138
138 % 10 = 8
So 74628-11-8 is a valid CAS Registry Number.

A CONVENIENT SYNTHESIS OF SUBSTITUTED γ-PYRONES

Koreeda, Masato,Akagi, Hiroshi

, p. 1197 - 1200 (2007/10/02)

An efficient and general synthetic method for various 2-mono- and 2,6-disubstituted γ-pyrones has been developed.This utilizes the C-acylation (70-85percent) of β-methoxy-α,β-enone lithium enolates 4 by acid chlorides 3 followed by the acid-catalyzed cycl
