Check Digit Verification of cas no
The CAS Registry Mumber 116909-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,0 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 116909-62:
(8*1)+(7*1)+(6*6)+(5*9)+(4*0)+(3*9)+(2*6)+(1*2)=137
137 % 10 = 7
So 116909-62-7 is a valid CAS Registry Number.

A NOVEL AND EFFICIENT ROUTE TO CHIRAL 2-SUBSTITUTED CARBOCYCLIC 5'-N-ETHYL-CARBOXAMIDO-ADENOSINE (C-NECA)
Chen, Jen,Grim, Michael,Rock, Caren,Chan, Kenneth
, p. 5543 - 5546 (2007/10/02)
A series of chiral 2-substituted-carbocyclic-NECA analogs was prepared in seven steps with an efficient resolution.The overall yield is good and can be applied to the other carbocyclic nucleosides.
