72046-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72046-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,4 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72046-40:
(7*7)+(6*2)+(5*0)+(4*4)+(3*6)+(2*4)+(1*0)=103
103 % 10 = 3
So 72046-40-3 is a valid CAS Registry Number.

Lithium keten thioacetalides. Factors influencing α- versus γ-alkylation
Murphy, William S.,Wattanasin, Sompong
, p. 2678 - 2682 (2007/10/02)
Alkylation of the lithium salt of the vinyl-1,3-dithian (2; R = CH 3) occurred exclusively at the α-carbon. However both α- and γ-alkylation was observed with the substrate (2; R = C 6H5). A systematic investigation reveal
