49820-64-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49820-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 49820-64:
(7*4)+(6*9)+(5*8)+(4*2)+(3*0)+(2*6)+(1*4)=146
146 % 10 = 6
So 49820-64-6 is a valid CAS Registry Number.

, p. 307 - 311 (2007/10/03)
In the reaction of oxalic acid hydrazide with isocyanates, new derivatives of semicarbazide were obtained [I-XII]. Cyclization of these derivatives with an aqueous 2% sodium hydroxide led to formation of new derivatives of Δ2-1,2,4-triazolin-5-
