Check Digit Verification of cas no

The CAS Registry Mumber 309751-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,7,5 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 309751-05:
(8*3)+(7*0)+(6*9)+(5*7)+(4*5)+(3*1)+(2*0)+(1*5)=141
141 % 10 = 1
So 309751-05-1 is a valid CAS Registry Number.
