Check Digit Verification of cas no

The CAS Registry Mumber 19323-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,2 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19323-75:
(7*1)+(6*9)+(5*3)+(4*2)+(3*3)+(2*7)+(1*5)=112
112 % 10 = 2
So 19323-75-2 is a valid CAS Registry Number.
