166277-17-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166277-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,2,7 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 166277-17:
(8*1)+(7*6)+(6*6)+(5*2)+(4*7)+(3*7)+(2*1)+(1*7)=154
154 % 10 = 4
So 166277-17-4 is a valid CAS Registry Number.
