3288-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3288-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3288-20:
(6*3)+(5*2)+(4*8)+(3*8)+(2*2)+(1*0)=88
88 % 10 = 8
So 3288-20-8 is a valid CAS Registry Number.

An efficient synthesis of 1,1-disubstituted hydrazines

Murakami,Yokoyama,Sasakura,Tamagawa

, p. 423 - 428 (2007/10/02)

1,1-disubstituted hydrazines were prepared from the corresponding 1,1-disubstituted ureas by means of the Hofmann rearrangement reaction. The yields were fairly good, except from the ureas susceptible to oxidation, and thus the present method represents an additional and efficient procedure for the synthesis of 1,1-disubstituted hydrazines.
