166239-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166239-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,2,3 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 166239-08:
(8*1)+(7*6)+(6*6)+(5*2)+(4*3)+(3*9)+(2*0)+(1*8)=143
143 % 10 = 3
So 166239-08-3 is a valid CAS Registry Number.
