Application
Building block for the synthesis of various natural products and pharmaceuticals.
Check Digit Verification of cas no
The CAS Registry Mumber 40031-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,3 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40031-15:
(7*4)+(6*0)+(5*0)+(4*3)+(3*1)+(2*1)+(1*5)=50
50 % 10 = 0
So 40031-15-0 is a valid CAS Registry Number.
