82820-46-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82820-46-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,2 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82820-46:
(7*8)+(6*2)+(5*8)+(4*2)+(3*0)+(2*4)+(1*6)=130
130 % 10 = 0
So 82820-46-0 is a valid CAS Registry Number.
