89471-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89471-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,7 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89471-19:
(7*8)+(6*9)+(5*4)+(4*7)+(3*1)+(2*1)+(1*9)=172
172 % 10 = 2
