103248-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103248-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,4 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103248-20:
(8*1)+(7*0)+(6*3)+(5*2)+(4*4)+(3*8)+(2*2)+(1*0)=80
80 % 10 = 0
So 103248-20-0 is a valid CAS Registry Number.
