Check Digit Verification of cas no

The CAS Registry Mumber 91644-89-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91644-89:
(7*9)+(6*1)+(5*6)+(4*4)+(3*4)+(2*8)+(1*9)=152
152 % 10 = 2
So 91644-89-2 is a valid CAS Registry Number.

Zinc promoted simple and convenient synthesis of carbamates: An easy access for amino group protection

Yadav,Reddy, Gondi Sudershan,Reddy, M. Muralidhar,Meshram

, p. 3259 - 3262 (1998)

Synthesis of alkyl, aryl, heterocyclic, carbohydrate and amino acid carbamates is described. The protection of the amino group in the presence of other functionality in amino acids demonstrates the importance of this method.

A practical synthesis of carbamates using an 'in-situ' generated polymer-supported chloroformate

Mormeneo, David,Llebaria, Amadeu,Delgado, Antonio

, p. 6831 - 6834 (2007/10/03)

A versatile method for the synthesis of carbamates from an 'in-situ' generated polymer-supported chloroformate resin is presented. BTC (bis-trichloromethyl carbonate) is used as phosgene equivalent to afford a supported chloroformate, which, by sequential 'one-pot' reaction with a variety of alcohols and amines, furnishes the corresponding carbamates in high yields and purities.
