The CAS Registry Mumber 477191-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,1,9 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 477191-90:
(8*4)+(7*7)+(6*7)+(5*1)+(4*9)+(3*1)+(2*9)+(1*0)=185
185 % 10 = 5
