Check Digit Verification of cas no
The CAS Registry Mumber 120665-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,6 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120665-66:
(8*1)+(7*2)+(6*0)+(5*6)+(4*6)+(3*5)+(2*6)+(1*6)=109
109 % 10 = 9
So 120665-66-9 is a valid CAS Registry Number.
