91239-72-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91239-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,3 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91239-72:
(7*9)+(6*1)+(5*2)+(4*3)+(3*9)+(2*7)+(1*2)=134
134 % 10 = 4
So 91239-72-4 is a valid CAS Registry Number.

Decarboxylation of Bridgehead Carboxylic Acids by the Barton Procedure

Della, Ernest W.,Tsanaktsidis, John

, p. 2061 - 2066 (2007/10/02)

Reductive decarboxylation of a series of bicyclic and polycyclic acids in which the carboxyl group is attached to the bridgehead position has been investigated.Conversion of the acids into thiohydroxamic esters occurs via reaction of the derived acid chlorides with N-hydroxypyridine-2-thione.Decomposition of the esters proceeds smoothly in boiling benzene in the presence of 1-butyl mercaptan to give the reduced product in high yield.The procedure appears to be generally applicable, and is unaffected by functional groups such as esters and acetals.
