Check Digit Verification of cas no

The CAS Registry Mumber 1220703-63-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,7,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1220703-63:
(9*1)+(8*2)+(7*2)+(6*0)+(5*7)+(4*0)+(3*3)+(2*6)+(1*3)=98
98 % 10 = 8
So 1220703-63-8 is a valid CAS Registry Number.

experimental part, p. 227 - 235 (2011/06/21)

A chimeric oligonucleotide tetramer and hexamer were synthesized by the phosphoramidite approach using a 2+2 and 3+3 strategy, respectively. The concept of convergent synthesis provides an efficient route toward the synthesis of longer chimeric oligonucle
