Check Digit Verification of cas no

The CAS Registry Mumber 27964-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,6 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27964-04:
(7*2)+(6*7)+(5*9)+(4*6)+(3*4)+(2*0)+(1*4)=141
141 % 10 = 1
So 27964-04-1 is a valid CAS Registry Number.

Synthesis and ribonuclease H related biochemical properties of α-anomeric 2'-deoxypyrimidine homooligomer and its phosphorothioate analog

Shinozuka, Kazuo,Yamada, Nobuaki,Nakamura, Akiko,Ozaki, Hiroaki,Sawai, Hiroaki

, p. 1843 - 1848 (1996)

Rnase H mediated degradation of RNA on the β-DNA·RNA duplex was inhibited by the presence of extra 2'-deoxypyrimidine homooligomer. The effect was dependent on the nature of the nucleobase, glycoside bond configuration, and the internucleotide linkage of the extra homooligomer used. Thus, α-anomeric 2'-deoxycytidylate phosphorothioate exhibited the most potent inhibitory effect (> 40%) on RNase H.
