81888-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81888-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,8 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81888-05:
(7*8)+(6*1)+(5*8)+(4*8)+(3*8)+(2*0)+(1*5)=163
163 % 10 = 3
So 81888-05-3 is a valid CAS Registry Number.
