The CAS Registry Mumber 19177-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,7 and 7 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 19177-74: (7*1)+(6*9)+(5*1)+(4*7)+(3*7)+(2*7)+(1*4)=133 133 % 10 = 3 So 19177-74-3 is a valid CAS Registry Number.
