Check Digit Verification of cas no

The CAS Registry Mumber 474248-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,2,4 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 474248-54:
(8*4)+(7*7)+(6*4)+(5*2)+(4*4)+(3*8)+(2*5)+(1*4)=169
169 % 10 = 9
So 474248-54-9 is a valid CAS Registry Number.

Novel assembly of cyclic ethers by coupling alpha-chlorosulfides and alcohols.

Inoue, Masayuki,Wang, Guang Xing,Wang, Jin,Hirama, Masahiro

, p. 3439 - 3442 (2007/10/03)

A novel protocol for assembling polycyclic ethers was developed and successfully applied to the synthesis of the EFGH ring system of ciguatoxin CTX3C. A key transformation involves construction of an O,S-acetal through coupling of alpha-chlorosulfide and
