Check Digit Verification of cas no

The CAS Registry Mumber 189129-08-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,1,2 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189129-08:
(8*1)+(7*8)+(6*9)+(5*1)+(4*2)+(3*9)+(2*0)+(1*8)=166
166 % 10 = 6
So 189129-08-6 is a valid CAS Registry Number.

6-Methyl-5-azacytidine - Synthesis, conformational properties and biological activity. A comparison of molecular conformation with 5- azacytidine

Hanna, Naeem B.,Zajicek, Jaroslav,Piskala, Alois

, p. 129 - 144 (2007/10/03)

The title compound was prepared by the isocyanate procedure and the trimethylsilyl method. The measurement of 1H NMR spectrum of 6-methyl-5- azacytidine (1) revealed a preference of γ(t) (46%) rotamer around C(5')- C(4') bond, a predominance of N conformation of the ribose ring (K(eq) 0.33) and a preference of syn conformation around the C-N glycosyl bond. An analogous measurement of 5-azacytidine has shown a preference of γ+ (60%) rotamer around the C(5')-C(4') bond, a predominance of N conformation of the fibose ring (K(eq) 0.41) and a preference of anti conformation around the C- N glycosyl bond 6-Methyl-5-azacytidine (1) inhibits the growth of bacteria E coli to the extent of 85% at 4000 μM concentration and the growth of LoVo/L, a human colon carcinoma cell line, to the extent of 30% at 100 μM concentration but did not inhibit L1210 cells at ≤ 100 μM concentration 6- Methyl-5-azacytidine (1) exhibited no in vitro antiviral activity at ≤ 1 μM concentration.
