164669-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164669-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,6,6 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 164669-32:
(8*1)+(7*6)+(6*4)+(5*6)+(4*6)+(3*9)+(2*3)+(1*2)=163
163 % 10 = 3
So 164669-32-3 is a valid CAS Registry Number.
