3117-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3117-41-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,1 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3117-41:
(6*3)+(5*1)+(4*1)+(3*7)+(2*4)+(1*1)=57
57 % 10 = 7
So 3117-41-7 is a valid CAS Registry Number.
