The CAS Registry Mumber 92544-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,5,4 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92544-85:
(7*9)+(6*2)+(5*5)+(4*4)+(3*4)+(2*8)+(1*5)=149
149 % 10 = 9
So 92544-85-9 is a valid CAS Registry Number.
