166758-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166758-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,7,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 166758-20:
(8*1)+(7*6)+(6*6)+(5*7)+(4*5)+(3*8)+(2*2)+(1*0)=169
169 % 10 = 9
So 166758-20-9 is a valid CAS Registry Number.
