Check Digit Verification of cas no

The CAS Registry Mumber 333970-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,9,7 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 333970-16:
(8*3)+(7*3)+(6*3)+(5*9)+(4*7)+(3*0)+(2*1)+(1*6)=144
144 % 10 = 4
So 333970-16-4 is a valid CAS Registry Number.

Prenyl and geranyl phenyl sulfone, a new carbon nucleophile for Mitsunobu-type alkylation

Uemoto, Kaori,Kawahito, Atsuko,Matsushita, Noriko,Sakamoto, Izumi,Kaku, Hiroto,Tsunoda, Tetsuto

, p. 905 - 907 (2001)

Cyanomethylenetrimethylphosphorane (CMMP), a new Mitsunobu reagent developed recently by the authors, mediated the alkylation of prenyl and geranyl phenyl sulfone with primary and secondary alcohols quite efficiently. Utilizing geranyl phenyl sulfone, norfaranal, an analog of the unique trail pheromone produced by Pharaoh's ant, was synthesized in a short number of steps.
