664308-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 664308-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,3,0 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 664308-50:
(8*6)+(7*6)+(6*4)+(5*3)+(4*0)+(3*8)+(2*5)+(1*0)=163
163 % 10 = 3
So 664308-50-3 is a valid CAS Registry Number.
