The CAS Registry Mumber 21646-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,4 and 6 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 21646-80: (7*2)+(6*1)+(5*6)+(4*4)+(3*6)+(2*8)+(1*0)=100 100 % 10 = 0 So 21646-80-0 is a valid CAS Registry Number.
