166043-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166043-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,0,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 166043-72:
(8*1)+(7*6)+(6*6)+(5*0)+(4*4)+(3*3)+(2*7)+(1*2)=127
127 % 10 = 7
So 166043-72-7 is a valid CAS Registry Number.
