Check Digit Verification of cas no
The CAS Registry Mumber 170997-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,9,9 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 170997-53:
(8*1)+(7*7)+(6*0)+(5*9)+(4*9)+(3*7)+(2*5)+(1*3)=172
172 % 10 = 2
So 170997-53-2 is a valid CAS Registry Number.
