249-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 249-06-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,4 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 249-06:
(5*2)+(4*4)+(3*9)+(2*0)+(1*6)=59
59 % 10 = 9
So 249-06-9 is a valid CAS Registry Number.
