120589-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120589-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,8 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120589-90:
(8*1)+(7*2)+(6*0)+(5*5)+(4*8)+(3*9)+(2*9)+(1*0)=124
124 % 10 = 4
So 120589-90-4 is a valid CAS Registry Number.
