109718-82-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109718-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,1 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109718-82:
(8*1)+(7*0)+(6*9)+(5*7)+(4*1)+(3*8)+(2*8)+(1*2)=143
143 % 10 = 3
So 109718-82-3 is a valid CAS Registry Number.
