Check Digit Verification of cas no

The CAS Registry Mumber 863592-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,5,9 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 863592-01:
(8*8)+(7*6)+(6*3)+(5*5)+(4*9)+(3*2)+(2*0)+(1*1)=192
192 % 10 = 2
So 863592-01-2 is a valid CAS Registry Number.

Nucleic acid related compounds. 127. Selective N-deacylation of N,O-peracylated nucleosides in superheated methanol

Nowak, Ireneusz,Conda-Sheridan, Martin,Robins, Morris J.

, p. 7455 - 7458 (2007/10/03)

Solutions of peracylated adenosine, cytidine, and related nucleoside derivatives undergo selective N-deacylation upon heating at elevated temperatures (oil bath ≥ 105 °C) in methanol. An increase in the bulk of the N-acyl group has little effect on the rate of N-deacylation but increases the N/O selectivity ratio. Extended heating is required for N-deacylation with arylcarboxylic acid derivatives. Contamination with acidic or basic reagent residues is avoided.
