Check Digit Verification of cas no

The CAS Registry Mumber 80680-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80680-41:
(7*8)+(6*0)+(5*6)+(4*8)+(3*0)+(2*4)+(1*1)=127
127 % 10 = 7
So 80680-41-7 is a valid CAS Registry Number.

A SIMPLIFIED STRATEGY FOR THE SYNTHESIS OF DIDEOXYRIBONUCLEOTIDE BLOCKS

Sadana, K. L.,Hruska, F. E.,Loewen, P. C.

, p. 3367 - 3370 (1981)

The rapid synthesis of dideoxyribonucleotide blocks in 60-85percent isolated yields has been achieved by combining the phosphorylation and condensation steps in a sequential reaction series which also allows the recovery of unreacted nucleotides.
