439292-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 439292-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,2,9 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 439292-92:
(8*4)+(7*3)+(6*9)+(5*2)+(4*9)+(3*2)+(2*9)+(1*2)=179
179 % 10 = 9
So 439292-92-9 is a valid CAS Registry Number.
