The CAS Registry Mumber 127761-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,6 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 127761-74:
(8*1)+(7*2)+(6*7)+(5*7)+(4*6)+(3*1)+(2*7)+(1*4)=144
144 % 10 = 4
So 127761-74-4 is a valid CAS Registry Number.
