104638-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104638-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,3 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104638-04:
(8*1)+(7*0)+(6*4)+(5*6)+(4*3)+(3*8)+(2*0)+(1*4)=102
102 % 10 = 2
So 104638-04-2 is a valid CAS Registry Number.

Diastereoselectivity and asymmetric induction in the Diels-Alder reaction of o-quinodimethanes
Charlton, James L.
, p. 720 - 725 (2007/10/02)
The extent of asymmetric induction in the bimolecular Diels-Alder reactions of chiral o-quinodimethanes with dimethyl fumarate, methyl acrylate, and maleic anhydride has been studied. o-Quinodimethanes with chiral α-alkoxy groups were prepared from 1-alko
