18963-88-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18963-88-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,6 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18963-88:
(7*1)+(6*8)+(5*9)+(4*6)+(3*3)+(2*8)+(1*8)=157
157 % 10 = 7
So 18963-88-7 is a valid CAS Registry Number.

Heating of 2-aminobenzamide (1) with benzoin (4) in the presence of anhydrous zinc chloride gave 2-(1-benzoylbenzylamino)benzamide (5a) which, on treatment with acetic anhydride, was transformed to 1,2-diphenyl-4,5-dihydropyrroloquinazolin-5-one (6
