163882-68-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163882-68-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,8 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 163882-68:
(8*1)+(7*6)+(6*3)+(5*8)+(4*8)+(3*2)+(2*6)+(1*8)=166
166 % 10 = 6
So 163882-68-6 is a valid CAS Registry Number.
