81888-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81888-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,8 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81888-04:
(7*8)+(6*1)+(5*8)+(4*8)+(3*8)+(2*0)+(1*4)=162
162 % 10 = 2
So 81888-04-2 is a valid CAS Registry Number.
