81522-26-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81522-26-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,2 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81522-26:
(7*8)+(6*1)+(5*5)+(4*2)+(3*2)+(2*2)+(1*6)=111
111 % 10 = 1
So 81522-26-1 is a valid CAS Registry Number.
