The CAS Registry Mumber 3190-43-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 0 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3190-43: (6*3)+(5*1)+(4*9)+(3*0)+(2*4)+(1*3)=70 70 % 10 = 0 So 3190-43-0 is a valid CAS Registry Number.
