Check Digit Verification of cas no
The CAS Registry Mumber 79761-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,7,6 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 79761-72:
(7*7)+(6*9)+(5*7)+(4*6)+(3*1)+(2*7)+(1*2)=181
181 % 10 = 1
So 79761-72-1 is a valid CAS Registry Number.

O-SILYLATED DIENOLATES IN ORGANIC SYNTHESIS: γ-SELECTIVE ALKYLATION OF UNSATURATED CARBONYL COMPOUNDS BY 1,3-DITHIENIUM FLUOROBORATE
Paterson, Ian,Price, Lee G.
, p. 2833 - 2836 (1981)
The alkylation of O-silylated dienolates of unsaturated aldehydes, ketones, and esters with 1,3-dithienium fluoroborate shows useful γ-selectivity.The γ-products are selectively protected 1,5-dicarbonyl compounds.
