109906-66-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109906-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,0 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109906-66:
(8*1)+(7*0)+(6*9)+(5*9)+(4*0)+(3*6)+(2*6)+(1*6)=143
143 % 10 = 3
So 109906-66-3 is a valid CAS Registry Number.
