137131-92-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137131-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,3 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137131-92:
(8*1)+(7*3)+(6*7)+(5*1)+(4*3)+(3*1)+(2*9)+(1*2)=111
111 % 10 = 1
So 137131-92-1 is a valid CAS Registry Number.
