Check Digit Verification of cas no
The CAS Registry Mumber 65281-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,2,8 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 65281-76:
(7*6)+(6*5)+(5*2)+(4*8)+(3*1)+(2*7)+(1*6)=137
137 % 10 = 7
So 65281-76-7 is a valid CAS Registry Number.

Studies related to biological detoxification of kraft pulp mill effluent. V. The synthesis of 12- and 14-chlorodehydroabietic acids and 12,14-dichlorodehydroabietic acid, fish-toxic diterpenes from kraft pulp mill effluent

An improved synthesis of the isomeric 12- and 14-chlorodehydroabietic acids and 12,14-dichlorodehydroabietic acid is described. The monochloro isomers were conveniently separated as the imidazole derivatives, and conversion of the latter to the free acids or their corresponding methyl esters could be achieved in high yield.
