Check Digit Verification of cas no

The CAS Registry Mumber 139125-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,2 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139125-56:
(8*1)+(7*3)+(6*9)+(5*1)+(4*2)+(3*5)+(2*5)+(1*6)=127
127 % 10 = 7
So 139125-56-7 is a valid CAS Registry Number.

Enantioselective alkylations of tributyltin enolates catalyzed by Cr(salen)CI: Access to enantiomerically enriched all-carbon quaternary centers

Doyle, Abigail G.,Jacobsen, Eric N.

, p. 62 - 63 (2007/10/03)

The catalytic asymmetric α-alkylation of tributyltin enolates with a range of primary alkyl halides is catalyzed by a chiral Cr(salen) complex. The reaction constitutes the first transition-metal-catalyzed system for α-alkylation of carbonyl substrates wi
