The CAS Registry Mumber 137233-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,3 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137233-99:
(8*1)+(7*3)+(6*7)+(5*2)+(4*3)+(3*3)+(2*9)+(1*9)=129
129 % 10 = 9
So 137233-99-9 is a valid CAS Registry Number.
