Check Digit Verification of cas no

The CAS Registry Mumber 138200-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,0 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138200-56:
(8*1)+(7*3)+(6*8)+(5*2)+(4*0)+(3*0)+(2*5)+(1*6)=103
103 % 10 = 3
So 138200-56-3 is a valid CAS Registry Number.

Asymmetric oxidation of β-ketoesters with benzoyl peroxide; enantioselective formation of protected tertiary alcohols

Lee,Oya,Snyder

, p. 5899 - 5902 (2007/10/02)

Asymmetric oxidation of β-ketoesters by the benzoyl peroxide quench of their lithioenamines formed with (S)-valine t-butyl esters has been accomplished with good enantioselectivity for the formation of tertiary benzoate esters. This procedure thus enables generation of tertiary alcohols in protected form.
