The CAS Registry Mumber 195451-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,4,5 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 195451-17:
(8*1)+(7*9)+(6*5)+(5*4)+(4*5)+(3*1)+(2*1)+(1*7)=153
153 % 10 = 3
So 195451-17-3 is a valid CAS Registry Number.
