Check Digit Verification of cas no
The CAS Registry Mumber 7438-72-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7438-72:
(6*7)+(5*4)+(4*3)+(3*8)+(2*7)+(1*2)=114
114 % 10 = 4
So 7438-72-4 is a valid CAS Registry Number.

Metalation of 1,3-Dithiolanes. Mercaptan Synthesis and Carbonyl Transposition
Wilson, Stephen R.,Georgiadis, Gregory M.,Khatri, Hiralal N.,Bartmess, John E.
, p. 3577 - 3583 (2007/10/02)
The reaction of 1,3-dithiolanes with n-butyllithium results in fragmentation to the corresponding thiocarbonyl compound followed by furhter reaction with n-butyllithium.All four types of thiocarbonyl reactions are observed: reduction, S-addition, C-addition, double addition.Synthetic applications of this reaction for the synthesis of secondary mercaptans and 1,2-carbonyl transposition (23 -> 24a-c) are described.
