The CAS Registry Mumber 177174-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,1,7 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 177174-13:
(8*1)+(7*7)+(6*7)+(5*1)+(4*7)+(3*4)+(2*1)+(1*3)=149
149 % 10 = 9
