103580-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103580-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,5,8 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103580-93:
(8*1)+(7*0)+(6*3)+(5*5)+(4*8)+(3*0)+(2*9)+(1*3)=104
104 % 10 = 4
So 103580-93-4 is a valid CAS Registry Number.
