80489-02-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80489-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,8 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80489-02:
(7*8)+(6*0)+(5*4)+(4*8)+(3*9)+(2*0)+(1*2)=137
137 % 10 = 7
So 80489-02-7 is a valid CAS Registry Number.
