The CAS Registry Mumber 193530-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,5,3 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193530-87:
(8*1)+(7*9)+(6*3)+(5*5)+(4*3)+(3*0)+(2*8)+(1*7)=149
149 % 10 = 9
So 193530-87-9 is a valid CAS Registry Number.
