131375-66-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131375-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,7 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131375-66:
(8*1)+(7*3)+(6*1)+(5*3)+(4*7)+(3*5)+(2*6)+(1*6)=111
111 % 10 = 1
So 131375-66-1 is a valid CAS Registry Number.
