889-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 889-92-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.Calculate Digit Verification of CAS Registry Number 889-92:
(5*8)+(4*8)+(3*9)+(2*9)+(1*2)=119
119 % 10 = 9
So 889-92-9 is a valid CAS Registry Number.
