Check Digit Verification of cas no
The CAS Registry Mumber 107166-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,1,6 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107166-99:
(8*1)+(7*0)+(6*7)+(5*1)+(4*6)+(3*6)+(2*9)+(1*9)=124
124 % 10 = 4
So 107166-99-4 is a valid CAS Registry Number.
