The CAS Registry Mumber 1083178-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,3,1,7 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1083178-44:
(9*1)+(8*0)+(7*8)+(6*3)+(5*1)+(4*7)+(3*8)+(2*4)+(1*4)=152
152 % 10 = 2
So 1083178-44-2 is a valid CAS Registry Number.
