Check Digit Verification of cas no

The CAS Registry Mumber 828272-16-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,8,2,7 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 828272-16:
(8*8)+(7*2)+(6*8)+(5*2)+(4*7)+(3*2)+(2*1)+(1*6)=178
178 % 10 = 8
So 828272-16-8 is a valid CAS Registry Number.

Novel examples of the N-methyl effect on cyclisations of N-Boc derivatives of amino alcohols. A theoretical study

Hamdach,El Hadrami,Testa,Gil,Zaballos-García,Sepúlveda-Arques,Arroyo,Domingo

, p. 12067 - 12073 (2004)

New examples of the N-methyl effect on the cyclisation of N-tert-butoxycarbonyl derivatives of amino alcohols are reported. Ab initio studies for the displacement step with formation of the five-membered heterocycle indicate that the increase of the nucleophile character of the carbonyl oxygen of the carbamate group with the N-methyl substitution is responsible for the acceleration of the cyclisation step.
