Check Digit Verification of cas no

The CAS Registry Mumber 109012-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,1 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109012-75:
(8*1)+(7*0)+(6*9)+(5*0)+(4*1)+(3*2)+(2*7)+(1*5)=91
91 % 10 = 1
So 109012-75-1 is a valid CAS Registry Number.

Asymmetric Michael Additions via SAMP-/RAMP-Hydrazones Enantioselective 1,4-Addition of Methyl Ketones to Knoevenagel Acceptors

Enders, Dieter,Demir, Ayhan S.,Rendenbach, Beatrice E. M.

, p. 1731 - 1736 (2007/10/02)

Asymmetric Michael addition of lithiated methyl ketone SAMP-hydrazones (S)-2 to 2-benzylidenemalonates and -dinitriles 3 followed by oxidative cleavage of the 1,4-adducts (SR)-4 by ozonolysis affords 2-substituted 4-oxo diesters and -dinitriles (R)-5 in good overall yields of 50-82percent and high enantiomeric excesses (ee >/= 95percent).
