The CAS Registry Mumber 69960-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,6 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69960-21:
(7*6)+(6*9)+(5*9)+(4*6)+(3*0)+(2*2)+(1*1)=170
170 % 10 = 0
So 69960-21-0 is a valid CAS Registry Number.
