65833-49-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65833-49-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,3 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 65833-49:
(7*6)+(6*5)+(5*8)+(4*3)+(3*3)+(2*4)+(1*9)=150
150 % 10 = 0
So 65833-49-0 is a valid CAS Registry Number.
