2939-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2939-53-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,3 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2939-53:
(6*2)+(5*9)+(4*3)+(3*9)+(2*5)+(1*3)=109
109 % 10 = 9
So 2939-53-9 is a valid CAS Registry Number.
