66875-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66875-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,7 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66875-29:
(7*6)+(6*6)+(5*8)+(4*7)+(3*5)+(2*2)+(1*9)=174
174 % 10 = 4
So 66875-29-4 is a valid CAS Registry Number.
