1609017-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1609017-45-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,0,1 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1609017-45:
(9*1)+(8*6)+(7*0)+(6*9)+(5*0)+(4*1)+(3*7)+(2*4)+(1*5)=149
149 % 10 = 9
So 1609017-45-9 is a valid CAS Registry Number.
