Check Digit Verification of cas no
The CAS Registry Mumber 84072-27-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,7 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84072-27:
(7*8)+(6*4)+(5*0)+(4*7)+(3*2)+(2*2)+(1*7)=125
125 % 10 = 5
So 84072-27-5 is a valid CAS Registry Number.

C-ACYLATION OF TERTIARY ENOLATES VIA DITHIOESTERS
Kende, Andrew S.,Becker, David A.
, p. 829 - 832 (2007/10/02)
The acylation of unsymmetrical ketones to β-ketoesters at a tertiary enolate center can be selectively achieved by way of the stable β-dithioketoesters (eq. 2).These undergo one-step or sequential conversion to the β-ketoesters using HgO-BF3.
