138406-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138406-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,0 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138406-54:
(8*1)+(7*3)+(6*8)+(5*4)+(4*0)+(3*6)+(2*5)+(1*4)=129
129 % 10 = 9
So 138406-54-9 is a valid CAS Registry Number.
