138405-24-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138405-24-0 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 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138405-24:
(8*1)+(7*3)+(6*8)+(5*4)+(4*0)+(3*5)+(2*2)+(1*4)=120
120 % 10 = 0
So 138405-24-0 is a valid CAS Registry Number.
