5923-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5923-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 5923-81:
(6*5)+(5*9)+(4*2)+(3*3)+(2*8)+(1*1)=109
109 % 10 = 9
So 5923-81-9 is a valid CAS Registry Number.
