107403-66-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107403-66-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,4,0 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 107403-66:
(8*1)+(7*0)+(6*7)+(5*4)+(4*0)+(3*3)+(2*6)+(1*6)=97
97 % 10 = 7
So 107403-66-7 is a valid CAS Registry Number.
