The CAS Registry Mumber 188444-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,4,4 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188444-03:
(8*1)+(7*8)+(6*8)+(5*4)+(4*4)+(3*4)+(2*0)+(1*3)=163
163 % 10 = 3
So 188444-03-3 is a valid CAS Registry Number.
