81664-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81664-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,6 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 81664-69:
(7*8)+(6*1)+(5*6)+(4*6)+(3*4)+(2*6)+(1*9)=149
149 % 10 = 9
So 81664-69-9 is a valid CAS Registry Number.
