The CAS Registry Mumber 161638-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,6,3 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 161638-01:
(8*1)+(7*6)+(6*1)+(5*6)+(4*3)+(3*8)+(2*0)+(1*1)=123
123 % 10 = 3
So 161638-01-3 is a valid CAS Registry Number.
