The CAS Registry Mumber 1185906-49-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,9,0 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1185906-49:
(9*1)+(8*1)+(7*8)+(6*5)+(5*9)+(4*0)+(3*6)+(2*4)+(1*9)=183
183 % 10 = 3
So 1185906-49-3 is a valid CAS Registry Number.
