109603-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109603-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,0 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109603-66:
(8*1)+(7*0)+(6*9)+(5*6)+(4*0)+(3*3)+(2*6)+(1*6)=119
119 % 10 = 9
So 109603-66-9 is a valid CAS Registry Number.
