Check Digit Verification of cas no

The CAS Registry Mumber 78983-31-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78983-31:
(7*7)+(6*8)+(5*9)+(4*8)+(3*3)+(2*3)+(1*1)=190
190 % 10 = 0
So 78983-31-0 is a valid CAS Registry Number.

N-ACYL PROTECTING GROUPS FOR DEOXYNUCLEOTSIDES A QUANTITATIVE AND COMPARATIVE STUDY

Koester, Hubert,Kulikowski, Konrad,Liese, Thomas,Heikens, Wiebke,Kohli, Vipin

, p. 363 - 369 (2007/10/02)

A detailed study in search for suitable N-acyldeoxy-nucleosides which could serve as building blocks for the stepwise synthesis of deoxyoligonucleotides was undertaken.Several acyl groups namely 4-t-butylphenylacetyl, 4-t-butylphenoxyacetyl, 4-chlorobenzoyl, 3,4-dichlorobenzoyl, 2-methyl-benzoyl, 2,4-dimethylbenzoyl, nicotinoyl, 4-t-butylbenzoyl and 4-phenylazobenzoyl have been used for the protection of the exocyclic amino groups of deoxynucleosides.Interesting data concerning the stability of N-acyl groups towards a potent deacylating system (0.2N NaOH/MeOH) are presented.
