Check Digit Verification of cas no
The CAS Registry Mumber 123075-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,7 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 123075-33:
(8*1)+(7*2)+(6*3)+(5*0)+(4*7)+(3*5)+(2*3)+(1*3)=92
92 % 10 = 2
So 123075-33-2 is a valid CAS Registry Number.
