Check Digit Verification of cas no

The CAS Registry Mumber 141422-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,4,2 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141422-22:
(8*1)+(7*4)+(6*1)+(5*4)+(4*2)+(3*2)+(2*2)+(1*2)=82
82 % 10 = 2
So 141422-22-2 is a valid CAS Registry Number.

Practical hydroxymethylation of aldehydes and ketones via pinacol cross-coupling reactions with paraformaldehyde

Park, Jeonghan,Pedersen, Steven F.

, p. 2069 - 2080 (2007/10/02)

A general and practical method for the direct hydroxymethylation of aldehydes and ketones via pinacol cross-coupling with paraformaldehyde is described. The reaction is promoted by vanadium(II) ions which are conveniently generated from the reduction of VCl3(THF)3 with zinc dust. Excellent yields of terminal diols are obtained and stereoselective coupling is observed with some chiral aldehydes and ketones.
