The CAS Registry Mumber 72251-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,5 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.Calculate Digit Verification of CAS Registry Number 72251-76:
(7*7)+(6*2)+(5*2)+(4*5)+(3*1)+(2*7)+(1*6)=114
114 % 10 = 4
So 72251-76-4 is a valid CAS Registry Number.
