Check Digit Verification of cas no
The CAS Registry Mumber 74965-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,6 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74965-36:
(7*7)+(6*4)+(5*9)+(4*6)+(3*5)+(2*3)+(1*6)=169

Intramolecular conversion of N,N-bis(2-picolyl)ureas to cyclic carbamates
Jakob, Uwe,Bannwarth, Willi
, p. 6340 - 6344 (2015/11/16)
Herein, we present a new methodology for preparing 6-membered ring carbamates from a CuI-promoted cyclization of N,N-bis(2-picolyl)amine substituted ureas. The reactions work best in the presence of up to five-fold excess of CuCl at room temper
