28949-66-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28949-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 28949-66:
(7*2)+(6*8)+(5*9)+(4*4)+(3*9)+(2*6)+(1*6)=168
168 % 10 = 8
So 28949-66-8 is a valid CAS Registry Number.
