83553-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83553-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,5 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83553-01:
(7*8)+(6*3)+(5*5)+(4*5)+(3*3)+(2*0)+(1*1)=129
129 % 10 = 9
So 83553-01-9 is a valid CAS Registry Number.
