83320-85-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83320-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83320-85:
(7*8)+(6*3)+(5*3)+(4*2)+(3*0)+(2*8)+(1*5)=118
118 % 10 = 8
So 83320-85-8 is a valid CAS Registry Number.
