Check Digit Verification of cas no

The CAS Registry Mumber 139618-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,1 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139618-02:
(8*1)+(7*3)+(6*9)+(5*6)+(4*1)+(3*8)+(2*0)+(1*2)=143
143 % 10 = 3
So 139618-02-3 is a valid CAS Registry Number.

Studies in alkylation of 3-methyl-3-sulfolene and thermolysis of resulting 2-alkyl-3-sulfolenes: Convenient synthesis of 1,2-disubstituted-1,3-dienes

Desai,Gore,Mayelvaganan,Padmakumar,Bhat

, p. 481 - 490 (1992)

Various 1,2-disubstituted-1,3-dienes have been synthesised through the alkylation of 3-methyl-3-sulfolene (1) followed by thermolysis of the resulting 2-alkyl-3-methyl-3-sulfolene (3,7). The alkylations with bulky iodides, particularly, containing ethylene ketal or phenyl sulfide moiety yield considerable amounts of rearranged 2-alkyl-3-methyl-2-sulfolene (4). The sulfolenes 3, 4 and 7 have been desulfonylated under mild conditions to yield corresponding 1,3-dienes.
