92173-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92173-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,7 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 92173-31:
(7*9)+(6*2)+(5*1)+(4*7)+(3*3)+(2*3)+(1*1)=124
124 % 10 = 4
So 92173-31-4 is a valid CAS Registry Number.
