693226-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 693226-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,3,2,2 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 693226-32:
(8*6)+(7*9)+(6*3)+(5*2)+(4*2)+(3*6)+(2*3)+(1*2)=173
173 % 10 = 3
So 693226-32-3 is a valid CAS Registry Number.
