The CAS Registry Mumber 852300-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,2,3,0 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 852300-58:
(8*8)+(7*5)+(6*2)+(5*3)+(4*0)+(3*0)+(2*5)+(1*8)=144
144 % 10 = 4
So 852300-58-4 is a valid CAS Registry Number.
