120583-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120583-97-3 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 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120583-97:
(8*1)+(7*2)+(6*0)+(5*5)+(4*8)+(3*3)+(2*9)+(1*7)=113
113 % 10 = 3
So 120583-97-3 is a valid CAS Registry Number.
