Check Digit Verification of cas no

The CAS Registry Mumber 112835-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,3 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112835-91:
(8*1)+(7*1)+(6*2)+(5*8)+(4*3)+(3*5)+(2*9)+(1*1)=113
113 % 10 = 3
So 112835-91-3 is a valid CAS Registry Number.

APPLICATION OF MICROORGANISMS AND ENZYMES TO THE SYNTHESIS OF CHIRAL CYCLOPENTANE AND BICYCLOOCTANE DERIVATIVES

Xie, Zhuo-Feng,Suemune, Hiroshi,Nakamura, Izumi,Sakai, Kiyoshi

, p. 4454 - 4459 (2007/10/02)

Optically active cyclopentane and bicyclooctane derivatives were synthesized by utilizing biochemical methods.Pseudomonas fluorescens lipase was found to be an effective enzyme for the enantioselective hydrolysis of monoacetoxy- and diacetoxycyclopentanes such as (+/-)-4a, (+/-)-5a, (+/-)-6a, and 7a.However,hydrolysis of bicyclooctane trans-acetate ((+/-)-8a) using this enzyme resulted low enantioselectivity.Optically pure (+)-8b for the synthesis of carbacyclin was obtained from (+/-)-8a by using porcine pancreatic lipase.Reduction of 3-acetyl-7-oxobicyclo-oct-2-ene with baker's yeast afforded a useful intermediate((+)-11b) for the synthesis of hirsutic acid.Keywords - enzymatic hydrolysis; enantioselective hydrolysis; bicyclo-octane; baker's yeast; carbacyclin; hirsutic acid
