Check Digit Verification of cas no
The CAS Registry Mumber 433335-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,3,3 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 433335-00:
(8*4)+(7*3)+(6*3)+(5*3)+(4*3)+(3*5)+(2*0)+(1*0)=113
113 % 10 = 3
So 433335-00-3 is a valid CAS Registry Number.

An Efficient Direct Access to Carbamates from Alcohols and TosMIC Mediated by Iodine in DMSO
Pogaku, Naresh,Krishna, Palakodety Radha,Prapurna, Y. Lakshmi
supporting information, p. 2039 - 2042 (2018/09/18)
A new approach for the synthesis of carbamates from alcohols and TosMIC promoted by iodine/DMSO system is reported. This method offers a one-step, direct and practical strategy for the rapid construction of carbamates under mild conditions. The reaction proceeds via sequential oxidation of isocyanide to isocyanate and nucleophilic addition of alcohols to isocyanate to afford the carbamates in high yields.
