138467-03-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138467-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,6 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138467-03:
(8*1)+(7*3)+(6*8)+(5*4)+(4*6)+(3*7)+(2*0)+(1*3)=145
145 % 10 = 5
So 138467-03-5 is a valid CAS Registry Number.
