The CAS Registry Mumber 120131-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,1,3 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120131-27:
(8*1)+(7*2)+(6*0)+(5*1)+(4*3)+(3*1)+(2*2)+(1*7)=53
53 % 10 = 3
So 120131-27-3 is a valid CAS Registry Number.
