The CAS Registry Mumber 201991-65-3 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 201991-65:
(8*2)+(7*0)+(6*1)+(5*9)+(4*9)+(3*1)+(2*6)+(1*5)=123
123 % 10 = 3
So 201991-65-3 is a valid CAS Registry Number.
