22494-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22494-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,9 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22494-84:
(7*2)+(6*2)+(5*4)+(4*9)+(3*4)+(2*8)+(1*4)=114
114 % 10 = 4
So 22494-84-4 is a valid CAS Registry Number.

Successive alkylation of 5-(3-phenylthioureido)-3H-imidazole-4-carboxamides with alkyl halides and chloroacetone gave (N-oxopropylimidazolyl)isothioureas, which were easily converted into derivatives of purine and imidazopyrazinone. In the case of ethyl 5
