103304-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103304-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,3,0 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103304-52:
(8*1)+(7*0)+(6*3)+(5*3)+(4*0)+(3*4)+(2*5)+(1*2)=65
65 % 10 = 5
So 103304-52-5 is a valid CAS Registry Number.
