The CAS Registry Mumber 201991-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,9,9 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 201991-66:
(8*2)+(7*0)+(6*1)+(5*9)+(4*9)+(3*1)+(2*6)+(1*6)=124
124 % 10 = 4
So 201991-66-4 is a valid CAS Registry Number.
