Check Digit Verification of cas no

The CAS Registry Mumber 183544-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,5,4 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 183544-65:
(8*1)+(7*8)+(6*3)+(5*5)+(4*4)+(3*4)+(2*6)+(1*5)=152
152 % 10 = 2
So 183544-65-2 is a valid CAS Registry Number.

Synthesis of cephalosporin derivatives utilizing the cephem triflate. 1. Introduction of 3-position substituents via a cycloaddition-fragmentation route

Kang, Han-Young,Lee, Sang Hak,Choi, Kyung Il.,Koh, Hun Yeong

, p. 7549 - 7552 (1996)

An efficient synthetic route for cephalosporin derivatives with various substituents at the 3-position has been developed. It involves cycloaddition with silyl enol ethers or silylketene acetals followed by fragmentation utilizing the 3-cephem triflate 1 as a starting material.
