Check Digit Verification of cas no

The CAS Registry Mumber 1173997-34-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,9 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1173997-34:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*9)+(3*7)+(2*3)+(1*4)=196

"One-pot" reductive lactone alkylation provides a concise asymmetric synthesis of chiral isoprenoid targets

Cao, Jia,Perlmutter, Patrick

supporting information, p. 4327 - 4329 (2013/09/24)

An efficient method, based on nucleophilic addition to lactones followed by modified in situ Clemmensen reduction, provides a short synthetic route to chiral isoprenoid targets. The efficacy of this method has been exemplified through the synthesis of several targets including the commercial fragrance Rosaphen, the side chain of Zaragozic acid C, the cotton leaf sex pheromone, and the side chains of vitamin E.
