62762-12-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62762-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,7,6 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 62762-12:
(7*6)+(6*2)+(5*7)+(4*6)+(3*2)+(2*1)+(1*2)=123
123 % 10 = 3
So 62762-12-3 is a valid CAS Registry Number.

Efficient Transformation of Trithio- and Triseleno-orthoesters into Ketene Dithio- and Diseleno-acetals
Nsunda, K. M.,Hevesi, L.
, p. 1000 - 1001 (2007/10/02)
Sequential treatment of trithio- and triseleno-orthoesters with a Lewis acid followed by a base leads to ketene dithio- and diseleno-acetals in good yield; SnCl4 or TiCl4 and (i-Pr)2EtN or Et3N are the most efficient reagents.
