The CAS Registry Mumber 1216254-45-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,6,2,5 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1216254-45:
(9*1)+(8*2)+(7*1)+(6*6)+(5*2)+(4*5)+(3*4)+(2*4)+(1*5)=123
123 % 10 = 3
