The CAS Registry Mumber 15172-51-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,7 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15172-51:
(7*1)+(6*5)+(5*1)+(4*7)+(3*2)+(2*5)+(1*1)=87
87 % 10 = 7
So 15172-51-7 is a valid CAS Registry Number.
