77630-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77630-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,3 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77630-51:
(7*7)+(6*7)+(5*6)+(4*3)+(3*0)+(2*5)+(1*1)=144
144 % 10 = 4
So 77630-51-4 is a valid CAS Registry Number.

A New Synthesis of Long Chain Acid Esters and Carbinols
Rao, S. Jagadishwar,Bhalerao, U. T.,Tilak, B. D.
, p. 208 - 211 (2007/10/02)
A versatile synthesis of difficulty accessible long chain acid esters and carbinols is described.The synthesis involves acylations at 2- and 5-positions of thiophene.Thioketalation of the resulting ketoesters followed by Raney nickel desulfurization yield acid esters which on LAH reduction give the corresponding carbinols.
