73280-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73280-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,8 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73280-47:
(7*7)+(6*3)+(5*2)+(4*8)+(3*0)+(2*4)+(1*7)=124
124 % 10 = 4
So 73280-47-4 is a valid CAS Registry Number.

Preparation of Methoxythiocarbonyl Substituted Ureas
Mack, Wilhelm
, p. 165 - 170 (2007/10/02)
The alkali metal salts 4 of phenylthiocarbamic O-methyl ester (1) yields with phosgene a carbonyl chloride (5), which is a suitable starting material for the preparation of the hitherto unknown group of methoxythiocarbonyl substituted ureas.In its reactio
