Check Digit Verification of cas no

The CAS Registry Mumber 188923-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,2 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188923-75:
(8*1)+(7*8)+(6*8)+(5*9)+(4*2)+(3*3)+(2*7)+(1*5)=193
193 % 10 = 3
So 188923-75-3 is a valid CAS Registry Number.
