The CAS Registry Mumber 190511-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,5,1 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 190511-69:
(8*1)+(7*9)+(6*0)+(5*5)+(4*1)+(3*1)+(2*6)+(1*9)=124
124 % 10 = 4
So 190511-69-4 is a valid CAS Registry Number.
