Check Digit Verification of cas no

The CAS Registry Mumber 174193-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,1,9 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 174193-14:
(8*1)+(7*7)+(6*4)+(5*1)+(4*9)+(3*3)+(2*1)+(1*4)=137
137 % 10 = 7
So 174193-14-7 is a valid CAS Registry Number.

Synthesis and properties of conformationally rigid cyclouridylic acid having a covalent bonding linker between the uracil 5-position and the 5 phosphate group

, p. 9515 - 9518 (2007/10/02)

A novel cyclouridylic acid 1 having a propylene bridge between the uracil 5 position and the 5′-phosphate group was synthesized. The structure of 1 was analyzed by 1H NMR, and CD spectroscopy, which suggested that the cyclonucleotide 1 was highly stabilized in a considerably rigid g′/C3′-endo conformation with the base orientation of and. The molecular mechanics calculation of 1 gave a similar conclusion.
