84857-56-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84857-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,5 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84857-56:
(7*8)+(6*4)+(5*8)+(4*5)+(3*7)+(2*5)+(1*6)=177
177 % 10 = 7
So 84857-56-7 is a valid CAS Registry Number.
