81904-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81904-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,0 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81904-26:
(7*8)+(6*1)+(5*9)+(4*0)+(3*4)+(2*2)+(1*6)=129
129 % 10 = 9
So 81904-26-9 is a valid CAS Registry Number.
