171613-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171613-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,6,1 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171613-40:
(8*1)+(7*7)+(6*1)+(5*6)+(4*1)+(3*3)+(2*4)+(1*0)=114
114 % 10 = 4
So 171613-40-4 is a valid CAS Registry Number.
