Check Digit Verification of cas no

The CAS Registry Mumber 238758-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,7,5 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 238758-38:
(8*2)+(7*3)+(6*8)+(5*7)+(4*5)+(3*8)+(2*3)+(1*8)=178
178 % 10 = 8
So 238758-38-8 is a valid CAS Registry Number.
