Check Digit Verification of cas no
The CAS Registry Mumber 97693-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,9 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97693-05:
(7*9)+(6*7)+(5*6)+(4*9)+(3*3)+(2*0)+(1*5)=185
185 % 10 = 5
So 97693-05-5 is a valid CAS Registry Number.
