Check Digit Verification of cas no
The CAS Registry Mumber 142404-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,0 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142404-83:
(8*1)+(7*4)+(6*2)+(5*4)+(4*0)+(3*4)+(2*8)+(1*3)=99
99 % 10 = 9
So 142404-83-9 is a valid CAS Registry Number.
