125247-82-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125247-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,4 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 125247-82:
(8*1)+(7*2)+(6*5)+(5*2)+(4*4)+(3*7)+(2*8)+(1*2)=117
117 % 10 = 7
So 125247-82-7 is a valid CAS Registry Number.
