Check Digit Verification of cas no

The CAS Registry Mumber 33895-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,9 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33895-23:
(7*3)+(6*3)+(5*8)+(4*9)+(3*5)+(2*2)+(1*3)=137
137 % 10 = 7
So 33895-23-7 is a valid CAS Registry Number.
