139903-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139903-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,0 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139903-80:
(8*1)+(7*3)+(6*9)+(5*9)+(4*0)+(3*3)+(2*8)+(1*0)=153
153 % 10 = 3
So 139903-80-3 is a valid CAS Registry Number.
