55503-64-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55503-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,0 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55503-64:
(7*5)+(6*5)+(5*5)+(4*0)+(3*3)+(2*6)+(1*4)=115
115 % 10 = 5
So 55503-64-5 is a valid CAS Registry Number.
