Check Digit Verification of cas no

The CAS Registry Mumber 214849-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,8,4 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 214849-18:
(8*2)+(7*1)+(6*4)+(5*8)+(4*4)+(3*9)+(2*1)+(1*8)=140
140 % 10 = 0
So 214849-18-0 is a valid CAS Registry Number.

Superacidic low temperature cyclization of terpenylphenyisulfones

Kulcitki, Veaceslav,Ungur, Nicon,Vlad, Pavel F.

, p. 11925 - 11934 (1998)

The superacidic cyclization of aliphatic and partially cyclized C10- C20 terpenylphenylsulfones proceeds structure-selectively and stereospecifically, affording α- or mixtures of α- and γ-isomers of completely cyclized terpenylphenylsulfones. The configuration of the phenylsuffonylmethylene group in the cyclized products is predetermined by the configuration of the allylic double bond in the starting compounds.
