Check Digit Verification of cas no

The CAS Registry Mumber 1138083-44-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,0,8 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1138083-44:
(9*1)+(8*1)+(7*3)+(6*8)+(5*0)+(4*8)+(3*3)+(2*4)+(1*4)=139
139 % 10 = 9
So 1138083-44-9 is a valid CAS Registry Number.

experimental part, p. 2116 - 2123 (2009/07/25)

We designed a novel 2′-O,5′-N bridged nucleic acid, 2′,5′-BNAON, whose sugar puckering was fixed to S-type conformation by an N-O linkage. A dimer unit formed from 2′,5′-BNAON-U and thymidine was synthesized via a coupling reaction b
