56503-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56503-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,0 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 56503-59:
(7*5)+(6*6)+(5*5)+(4*0)+(3*3)+(2*5)+(1*9)=124
124 % 10 = 4
So 56503-59-4 is a valid CAS Registry Number.
