166545-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166545-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,5,4 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 166545-87:
(8*1)+(7*6)+(6*6)+(5*5)+(4*4)+(3*5)+(2*8)+(1*7)=165
165 % 10 = 5
So 166545-87-5 is a valid CAS Registry Number.
