The CAS Registry Mumber 119873-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,7 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 119873-06:
(8*1)+(7*1)+(6*9)+(5*8)+(4*7)+(3*3)+(2*0)+(1*6)=152
152 % 10 = 2
So 119873-06-2 is a valid CAS Registry Number.
