109686-66-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109686-66-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,8 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109686-66:
(8*1)+(7*0)+(6*9)+(5*6)+(4*8)+(3*6)+(2*6)+(1*6)=160
160 % 10 = 0
So 109686-66-0 is a valid CAS Registry Number.
