120400-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120400-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,0 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120400-31:
(8*1)+(7*2)+(6*0)+(5*4)+(4*0)+(3*0)+(2*3)+(1*1)=49
49 % 10 = 9
So 120400-31-9 is a valid CAS Registry Number.
