The CAS Registry Mumber 198219-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,2,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 198219-71:
(8*1)+(7*9)+(6*8)+(5*2)+(4*1)+(3*9)+(2*7)+(1*1)=175
175 % 10 = 5
So 198219-71-5 is a valid CAS Registry Number.
