Check Digit Verification of cas no
The CAS Registry Mumber 17695-32-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,9 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17695-32:
(7*1)+(6*7)+(5*6)+(4*9)+(3*5)+(2*3)+(1*2)=138
138 % 10 = 8
So 17695-32-8 is a valid CAS Registry Number.
