Check Digit Verification of cas no
The CAS Registry Mumber 1102373-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,2,3,7 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1102373-43:
(9*1)+(8*1)+(7*0)+(6*2)+(5*3)+(4*7)+(3*3)+(2*4)+(1*3)=92
92 % 10 = 2
So 1102373-43-2 is a valid CAS Registry Number.
