139560-99-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139560-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,6 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139560-99:
(8*1)+(7*3)+(6*9)+(5*5)+(4*6)+(3*0)+(2*9)+(1*9)=159
159 % 10 = 9
So 139560-99-9 is a valid CAS Registry Number.
