93697-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93697-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93697-21:
(7*9)+(6*3)+(5*6)+(4*9)+(3*7)+(2*2)+(1*1)=173
173 % 10 = 3
So 93697-21-3 is a valid CAS Registry Number.
