3247-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3247-38-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.Calculate Digit Verification of CAS Registry Number 3247-38:
(6*3)+(5*2)+(4*4)+(3*7)+(2*3)+(1*8)=79
79 % 10 = 9
So 3247-38-9 is a valid CAS Registry Number.
