Check Digit Verification of cas no

The CAS Registry Mumber 309931-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,9,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 309931-83:
(8*3)+(7*0)+(6*9)+(5*9)+(4*3)+(3*1)+(2*8)+(1*3)=157
157 % 10 = 7
So 309931-83-7 is a valid CAS Registry Number.

Asymmetric Diels-Alder reaction of 1,3-butadienes with (-)-dimenthyl fumarate in the presence of BBr3 and BBr3·OEt 2

Mamedov

, p. 184 - 187 (2007)

Asymmetric synthesis of substituted cyclohexenes was performed by [4+2]-cycloaddition of (-)-dimenthyl fumarate to 1,3-butadienes in the presence of BBr3 and BBr3·OEt2. The latter are efficient catalysts for this reaction.
