Check Digit Verification of cas no
The CAS Registry Mumber 180303-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,3,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180303-05:
(8*1)+(7*8)+(6*0)+(5*3)+(4*0)+(3*3)+(2*0)+(1*5)=93
