Check Digit Verification of cas no

The CAS Registry Mumber 98553-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,5 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98553-87:
(7*9)+(6*8)+(5*5)+(4*5)+(3*3)+(2*8)+(1*7)=188
188 % 10 = 8
So 98553-87-8 is a valid CAS Registry Number.

Stereoselectivity in the Synthesis of Enol Esters from Chloromercurio Aldehydes and Acyl Chlorides

Fukuda, Wakichi,Sato, Hozumi,Kakiuchi, Hiroshi

, p. 751 - 756 (1986)

Reactions of chloromercurio aldehydes with acyl chlorides gave a variety of (Z)- and (E)-enol esters.The Z/E ratio of the enol esters is dependent on the structure of chloromercurio aldehydes but independent of that of acyl chlorides.Z-Rich enol esters were prepared by acylation of 2-chloromercurio aldehydes derived from propanal, butanal, and 2-phenylethanal, while E-rich 1-acyloxy-1,3-butadiene was obtained by acylation of (E)-4-chloromercurio-2-butenal.Reaction mechanisms for the stereoselective formation of these enol esters are discussed together with the isomer composition of starting enol acetates from which the chloromercurio aldehydes were prepared.
