The CAS Registry Mumber 161450-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,4,5 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 161450-61:
(8*1)+(7*6)+(6*1)+(5*4)+(4*5)+(3*0)+(2*6)+(1*1)=109
109 % 10 = 9
So 161450-61-9 is a valid CAS Registry Number.
