The CAS Registry Mumber 922166-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,2,1,6 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 922166-71:
(8*9)+(7*2)+(6*2)+(5*1)+(4*6)+(3*6)+(2*7)+(1*1)=160
160 % 10 = 0
So 922166-71-0 is a valid CAS Registry Number.
