120040-68-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120040-68-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,4 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 120040-68:
(8*1)+(7*2)+(6*0)+(5*0)+(4*4)+(3*0)+(2*6)+(1*8)=58
58 % 10 = 8
So 120040-68-8 is a valid CAS Registry Number.
