66949-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66949-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66949-22:
(7*6)+(6*6)+(5*9)+(4*4)+(3*9)+(2*2)+(1*2)=172
172 % 10 = 2
So 66949-22-2 is a valid CAS Registry Number.
