82507-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82507-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,0 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82507-47:
(7*8)+(6*2)+(5*5)+(4*0)+(3*7)+(2*4)+(1*7)=129
129 % 10 = 9
So 82507-47-9 is a valid CAS Registry Number.
