Check Digit Verification of cas no

The CAS Registry Mumber 143839-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,3 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143839-00:
(8*1)+(7*4)+(6*3)+(5*8)+(4*3)+(3*9)+(2*0)+(1*0)=133
133 % 10 = 3
So 143839-00-3 is a valid CAS Registry Number.

Electrooxidative Functionalizations of Dehydroabietic Acid

Uneyama, Kenji,Katayama, Tatsuo,Torii, Sigeru

, p. 3043 - 3044 (1987)

Dehydroabietic acid methyl ester (1) was converted into 7-acetoxydehydroabietic acid methyl ester by direct electrooxidation in acetic acid and 7-oxodehydroabietic acid methyl ester by ruthenium dioxide-mediated oxidation.Non-Kolbe type electrodecarboxylation of 1 resulted in the introduction of a double bond into the ring A of 1.

REGIOSELECTIVE REACTIONS OF ABIETIC ACID METHYL ESTER

Escudero, Javier,Marquez, Cecilio,Rabanal, Rosa Ma,Valverde, S.

, p. 3167 - 3170 (2007/10/02)

Ozonolysis of abietic acid methyl ester 1 in the presence of mercuric acetate afforded the 13,14-seco-derivative in fair yield (50percent).Selenium dioxide oxidation of 1 in t-butanol gave 9-α-hydroxy-abietic acid methyl ester 6, dehydroabietic acid methyl ester 4 and its 7α-hydroxy-derivative 4b.
