139388-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139388-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,8 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139388-53:
(8*1)+(7*3)+(6*9)+(5*3)+(4*8)+(3*8)+(2*5)+(1*3)=167
167 % 10 = 7
So 139388-53-7 is a valid CAS Registry Number.
