189889-88-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189889-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,8 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.Calculate Digit Verification of CAS Registry Number 189889-88:
(8*1)+(7*8)+(6*9)+(5*8)+(4*8)+(3*9)+(2*8)+(1*8)=241
241 % 10 = 1
So 189889-88-1 is a valid CAS Registry Number.
