Check Digit Verification of cas no

The CAS Registry Mumber 250695-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,6,9 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 250695-50:
(8*2)+(7*5)+(6*0)+(5*6)+(4*9)+(3*5)+(2*5)+(1*0)=142
142 % 10 = 2
So 250695-50-2 is a valid CAS Registry Number.

Asymmetric synthesis of 4'-methyl-2',3'-dideoxynucleosides

Luzzio, Frederick A.,Mayorov, Alexander V.,Menes, Michael E.,Champion Jr., William L.

, p. 1977 - 1984 (2007/10/03)

The stereoselective preparation of a 4-methyl-2,3-dideoxyribose derivative is described which utilizes (-)-menthyl pyruvate as a chiral template and an organocerium addition as the key carbon-carbon bond-forming step. The 4-methyl-2,3-dideoxyribose derivative was used as a substrate for a Vorbruggen pyrimidine glycosylation giving an α,β-mixture of 4'-methyl- 2',3'-dideoxynucleosides.
