139870-42-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139870-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,8,7 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139870-42:
(8*1)+(7*3)+(6*9)+(5*8)+(4*7)+(3*0)+(2*4)+(1*2)=161
161 % 10 = 1
So 139870-42-1 is a valid CAS Registry Number.

supporting information; experimental part, p. 2242 - 2245 (2010/08/05)

The first synthesis of 4′-selenothymidine (1), a novel DNA building block, and 4′-seleno-AZT (2) was accomplished from 2-deoxy-d-ribose via stereoselective formation of 2-deoxy-4-seleno-d-furanose 17 and a Pummerer-type base condensation as key steps. 4′-
