82838-72-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82838-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,3 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82838-72:
(7*8)+(6*2)+(5*8)+(4*3)+(3*8)+(2*7)+(1*2)=160
160 % 10 = 0
So 82838-72-0 is a valid CAS Registry Number.
