Check Digit Verification of cas no

The CAS Registry Mumber 178380-05-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,3,8 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 178380-05:
(8*1)+(7*7)+(6*8)+(5*3)+(4*8)+(3*0)+(2*0)+(1*5)=157
157 % 10 = 7
So 178380-05-7 is a valid CAS Registry Number.
