2117-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2117-42-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2117-42:
(6*2)+(5*1)+(4*1)+(3*7)+(2*4)+(1*2)=52
52 % 10 = 2
So 2117-42-2 is a valid CAS Registry Number.
