17697-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17697-93-7 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 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17697-93:
(7*1)+(6*7)+(5*6)+(4*9)+(3*7)+(2*9)+(1*3)=157
157 % 10 = 7
So 17697-93-7 is a valid CAS Registry Number.
