164526-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164526-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,5,2 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 164526-20:
(8*1)+(7*6)+(6*4)+(5*5)+(4*2)+(3*6)+(2*2)+(1*0)=129
129 % 10 = 9
So 164526-20-9 is a valid CAS Registry Number.
