Check Digit Verification of cas no

The CAS Registry Mumber 308279-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,2,7 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 308279-01:
(8*3)+(7*0)+(6*8)+(5*2)+(4*7)+(3*9)+(2*0)+(1*1)=138
138 % 10 = 8
So 308279-01-8 is a valid CAS Registry Number.

[2+2] Cycloaddition of chlorosulfonyl isocyanate to allenyl-sugar ethers

Lysek, Robert,Furman, Bartlomiej,Kaluza, Zbigniew,Frelek, Jadwiga,Suwinska, Kinga,Urbanczyk-Lipkowska, Zofia,Chmielewski, Marek

, p. 3131 - 3150 (2007/10/03)

The direction and magnitude of asymmetric induction in the [2+2] cycloaddition of chlorosulfonyl isocyanate to 3-O-allenyl-α-D-xylofuranoses was investigated. It is shown that gem terminal dimethylallenes react more readily than methyl free congeners. The configuration of adducts was established by X-ray and CD-spectroscopy of alkylidene cephams. A stereochemical model of the transition state for the [2+2] cycloaddition of chlorosulfonyl isocyanate and allenyl ethers is proposed, based on the lowest energy conformation of the cumulene.
