870003-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 870003-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,0,0 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 870003-07:
(8*8)+(7*7)+(6*0)+(5*0)+(4*0)+(3*3)+(2*0)+(1*7)=129
129 % 10 = 9
So 870003-07-9 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
