83300-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83300-63-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,0 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83300-63:
(7*8)+(6*3)+(5*3)+(4*0)+(3*0)+(2*6)+(1*3)=104
104 % 10 = 4
So 83300-63-4 is a valid CAS Registry Number.
