Check Digit Verification of cas no

The CAS Registry Mumber 74285-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,8 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74285-09:
(7*7)+(6*4)+(5*2)+(4*8)+(3*5)+(2*0)+(1*9)=139
139 % 10 = 9
So 74285-09-9 is a valid CAS Registry Number.

Electrolytic Decarboxylation. 6. A Convenient Synthesis of 3-(cis-3-Hexenyl)-2-cyclopentenone, a Precursor of cis-Jasmone Synthesis

Torii, Sigeru,Tanaka, Hideo,Inokuchi, Tsutomu,Tomozane, Kazuo

, p. 3947 - 3948 (1982)

A regioselective electro-acetoxylation of 1-(cis-3-hexenyl)-2-cyclopentene-1-carboxylic acid in a Et3N-AcOH-AcOEt-t-BuOH-(Pt electrodes) system afforded 3-acetoxy-1-(cis-3-hexenyl)-1-cyclopentene (7a) (98percent).Alkaline hydrolysis of 7a followed by the oxidation with chromium trioxide gave the desired 3-(cis-3-hexenyl)-2-cyclopentenone smoothly.
