The CAS Registry Mumber 2153-21-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.Calculate Digit Verification of CAS Registry Number 2153-21:
(6*2)+(5*1)+(4*5)+(3*3)+(2*2)+(1*1)=51
51 % 10 = 1
So 2153-21-1 is a valid CAS Registry Number.
