109384-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109384-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,8 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109384-70:
(8*1)+(7*0)+(6*9)+(5*3)+(4*8)+(3*4)+(2*7)+(1*0)=135
135 % 10 = 5
So 109384-70-5 is a valid CAS Registry Number.
