122604-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122604-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,0 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 122604-40:
(8*1)+(7*2)+(6*2)+(5*6)+(4*0)+(3*4)+(2*4)+(1*0)=84
84 % 10 = 4
So 122604-40-4 is a valid CAS Registry Number.
