138254-43-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138254-43-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,5 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 138254-43:
(8*1)+(7*3)+(6*8)+(5*2)+(4*5)+(3*4)+(2*4)+(1*3)=130
130 % 10 = 0
So 138254-43-0 is a valid CAS Registry Number.
