The CAS Registry Mumber 20965-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,6 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20965-45:
(7*2)+(6*0)+(5*9)+(4*6)+(3*5)+(2*4)+(1*5)=111
111 % 10 = 1
So 20965-45-1 is a valid CAS Registry Number.
