120400-29-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120400-29-5 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, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120400-29:
(8*1)+(7*2)+(6*0)+(5*4)+(4*0)+(3*0)+(2*2)+(1*9)=55
55 % 10 = 5
So 120400-29-5 is a valid CAS Registry Number.
