Check Digit Verification of cas no

The CAS Registry Mumber 945374-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,3,7 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 945374-90:
(8*9)+(7*4)+(6*5)+(5*3)+(4*7)+(3*4)+(2*9)+(1*0)=203
203 % 10 = 3
So 945374-90-3 is a valid CAS Registry Number.

Catalytic, asymmetric synthesis of 1,4-benzoxazinones: A remarkably enantioselective route to α-amino acid derivatives from o-benzoquinone imides

Wolfer, Jamison,Bekele, Tefsit,Abraham, Ciby J.,Dogo-Isonagie, Cajetan,Lectka, Thomas

, p. 7398 - 7400 (2008/01/27)

(Chemical Equation Presented) Cycloaddition of o-benzoquinone imides with chiral ketene enolates derived from cinchona alkaloid catalysts is the basis of a catalytic asymmetric synthesis of 1,4-benzoxazinones and 1,4-benzoxazines. The resulting cycloadduc
