The CAS Registry Mumber 5965-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,6 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5965-21:
(6*5)+(5*9)+(4*6)+(3*5)+(2*2)+(1*1)=119
119 % 10 = 9
So 5965-21-9 is a valid CAS Registry Number.
