81546-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81546-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,4 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81546-70:
(7*8)+(6*1)+(5*5)+(4*4)+(3*6)+(2*7)+(1*0)=135
135 % 10 = 5
So 81546-70-5 is a valid CAS Registry Number.
