Check Digit Verification of cas no
The CAS Registry Mumber 166049-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,0,4 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 166049-80:
(8*1)+(7*6)+(6*6)+(5*0)+(4*4)+(3*9)+(2*8)+(1*0)=145
145 % 10 = 5
So 166049-80-5 is a valid CAS Registry Number.
