Check Digit Verification of cas no
The CAS Registry Mumber 127199-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,9 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 127199-44:
(8*1)+(7*2)+(6*7)+(5*1)+(4*9)+(3*9)+(2*4)+(1*4)=144
144 % 10 = 4
So 127199-44-4 is a valid CAS Registry Number.
