247256-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247256-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,2,5 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 247256-66:
(8*2)+(7*4)+(6*7)+(5*2)+(4*5)+(3*6)+(2*6)+(1*6)=152
152 % 10 = 2
So 247256-66-2 is a valid CAS Registry Number.
