Check Digit Verification of cas no
The CAS Registry Mumber 2403-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,0 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2403-90:
(6*2)+(5*4)+(4*0)+(3*3)+(2*9)+(1*0)=59
