Check Digit Verification of cas no

The CAS Registry Mumber 83790-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,9 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83790-75:
(7*8)+(6*3)+(5*7)+(4*9)+(3*0)+(2*7)+(1*5)=164
164 % 10 = 4
So 83790-75-4 is a valid CAS Registry Number.

Reaction Behaviour of Amides with Carbondisulphide and Isothiocyanates

Richter, M.,Strauss, K.,Schaedler, H.-D.,Augustin, M.

, p. 625 - 630 (2007/10/02)

Reactions of substituted arylamides, hetarylamides and furylacrylicamide 1 with carbon disulphide present a possibility to synthesize imino-dithiocarbonic-S,S'-diester 5.The mechanism of the reaction and the reaction conditions are investigated.Quantum chemical investigations by simple HMO-method in connection with the experimental results describe the reaction in dependence upon the influence of substituent in 2- and 4-position to the phenylring.Further more is describe the reaction of amide with isothiocyanates to thiourea 6 and isothiourea 7. The structures of the final products are determined by analytical dates.
