81255-47-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81255-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,5 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81255-47:
(7*8)+(6*1)+(5*2)+(4*5)+(3*5)+(2*4)+(1*7)=122
122 % 10 = 2
So 81255-47-2 is a valid CAS Registry Number.
