160662-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160662-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,6,6 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 160662-63:
(8*1)+(7*6)+(6*0)+(5*6)+(4*6)+(3*2)+(2*6)+(1*3)=125
125 % 10 = 5
So 160662-63-5 is a valid CAS Registry Number.
