Check Digit Verification of cas no

The CAS Registry Mumber 1021422-80-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,4,2 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1021422-80:
(9*1)+(8*0)+(7*2)+(6*1)+(5*4)+(4*2)+(3*2)+(2*8)+(1*0)=79
79 % 10 = 9
So 1021422-80-9 is a valid CAS Registry Number.

Straightforward carbamoylation of nucleophilic compounds employing organic azides, phosphines, and aqueous trialkylammonium hydrogen carbonate

Yagodkin, Andrey,L?schcke, Kerstin,Weisell, Janne,Azhayev, Alex

experimental part, p. 2210 - 2221 (2010/04/29)

In the presence of aqueous trialkylammonium hydrogen carbonate, the Staudinger reaction leads to the intermediate formation of the corresponding isocyanate, which, in turn, reacts further with a nucleophilic reagent also present in the mixture and results in carbamoylation with good yield. On the basis of this reaction a practical carbamoylation procedure was devised and a comparative study on suitability of different solvents and phosphorus (III) derivatives for carbamoylation reaction was conducted. The versatility of the method was demonstrated by examples with different classes of nucleophilic compounds that included the aminomethyl resin and natural compounds that display poor solubility in organic solvents.
