2923-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2923-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2923-21:
(6*2)+(5*9)+(4*2)+(3*3)+(2*2)+(1*1)=79
79 % 10 = 9
So 2923-21-9 is a valid CAS Registry Number.
