165388-00-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 165388-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,3,8 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 165388-00:
(8*1)+(7*6)+(6*5)+(5*3)+(4*8)+(3*8)+(2*0)+(1*0)=151
151 % 10 = 1
So 165388-00-1 is a valid CAS Registry Number.
