17965-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17965-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,6 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17965-56:
(7*1)+(6*7)+(5*9)+(4*6)+(3*5)+(2*5)+(1*6)=149
149 % 10 = 9
So 17965-56-9 is a valid CAS Registry Number.
