Check Digit Verification of cas no

The CAS Registry Mumber 40990-10-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,9 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40990-10:
(7*4)+(6*0)+(5*9)+(4*9)+(3*0)+(2*1)+(1*0)=111
111 % 10 = 1
So 40990-10-1 is a valid CAS Registry Number.

Chelation-Controlled Facially Selective Cyclocondensation Reactions of Chiral Alkoxy Aldehydes: Syntheses of a Mouse Androgen and of a Carbon-Linked Disaccharide

Danishefsky, Samuel J.,Pearson, William H.,Harvey, Daniel F.,Maring, Clarence J.,Springer, James P.

, p. 1256 - 1268 (2007/10/02)

Magnesium bromide in tetrahydrofuran catalyzes the cycloaddition of a variety of chiral alkoxy aldehydes with activated butadienes.The stereochemistry of these products is such that they can be rationalized as arising from a reacting conformer in which th
