161170-88-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161170-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,7 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 161170-88:
(8*1)+(7*6)+(6*1)+(5*1)+(4*7)+(3*0)+(2*8)+(1*8)=113
113 % 10 = 3
So 161170-88-3 is a valid CAS Registry Number.
