The CAS Registry Mumber 69291-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,2,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69291-50:
(7*6)+(6*9)+(5*2)+(4*9)+(3*1)+(2*5)+(1*0)=155
155 % 10 = 5
So 69291-50-5 is a valid CAS Registry Number.
