296246-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 296246-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,6,2,4 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 296246-80:
(8*2)+(7*9)+(6*6)+(5*2)+(4*4)+(3*6)+(2*8)+(1*0)=175
175 % 10 = 5
So 296246-80-5 is a valid CAS Registry Number.
