138509-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138509-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138509-53:
(8*1)+(7*3)+(6*8)+(5*5)+(4*0)+(3*9)+(2*5)+(1*3)=142
142 % 10 = 2
So 138509-53-2 is a valid CAS Registry Number.
