The CAS Registry Mumber 7381-15-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,8 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7381-15:
(6*7)+(5*3)+(4*8)+(3*1)+(2*1)+(1*5)=99
99 % 10 = 9
So 7381-15-9 is a valid CAS Registry Number.
