Check Digit Verification of cas no

The CAS Registry Mumber 1256705-58-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,7,0 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1256705-58:
(9*1)+(8*2)+(7*5)+(6*6)+(5*7)+(4*0)+(3*5)+(2*5)+(1*8)=164
164 % 10 = 4
So 1256705-58-4 is a valid CAS Registry Number.
