82864-46-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82864-46-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,6 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82864-46:
(7*8)+(6*2)+(5*8)+(4*6)+(3*4)+(2*4)+(1*6)=158
158 % 10 = 8
So 82864-46-8 is a valid CAS Registry Number.
