103438-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103438-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,3 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103438-45:
(8*1)+(7*0)+(6*3)+(5*4)+(4*3)+(3*8)+(2*4)+(1*5)=95
95 % 10 = 5
So 103438-45-5 is a valid CAS Registry Number.
