103035-35-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103035-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,0,3 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103035-35:
(8*1)+(7*0)+(6*3)+(5*0)+(4*3)+(3*5)+(2*3)+(1*5)=64
64 % 10 = 4
So 103035-35-4 is a valid CAS Registry Number.
