1013404-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1013404-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,3,4,0 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1013404-75:
(9*1)+(8*0)+(7*1)+(6*3)+(5*4)+(4*0)+(3*4)+(2*7)+(1*5)=85
85 % 10 = 5
So 1013404-75-5 is a valid CAS Registry Number.
