The CAS Registry Mumber 212553-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,5,5 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 212553-45:
(8*2)+(7*1)+(6*2)+(5*5)+(4*5)+(3*3)+(2*4)+(1*5)=102
102 % 10 = 2
So 212553-45-2 is a valid CAS Registry Number.
