Check Digit Verification of cas no

The CAS Registry Mumber 174193-16-9 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 174193-16:
(8*1)+(7*7)+(6*4)+(5*1)+(4*9)+(3*3)+(2*1)+(1*6)=139
139 % 10 = 9
So 174193-16-9 is a valid CAS Registry Number.

Synthesis and properties of conformationally rigid cyclouridylic acids having covalent bonding linkers between the uracil 5-position and the 5′-phosphate group

, p. 1023 - 1032 (2007/10/03)

Conformationally rigid cyclouridylic acid derivatives 2 and 3 having ethylene and propylene bridges, respectively, between the uracil 5-position and the 5′-phosphate group were synthesized. These intramolecularly cyclized compounds have predominantly the ribose pucker of C3′-endo and the g+ orientation around the C4′-C5′ bond. Copyright
