53138-51-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53138-51-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,3 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 53138-51:
(7*5)+(6*3)+(5*1)+(4*3)+(3*8)+(2*5)+(1*1)=105
105 % 10 = 5
So 53138-51-5 is a valid CAS Registry Number.
