139448-95-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139448-95-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,4 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139448-95:
(8*1)+(7*3)+(6*9)+(5*4)+(4*4)+(3*8)+(2*9)+(1*5)=166
166 % 10 = 6
So 139448-95-6 is a valid CAS Registry Number.
