Check Digit Verification of cas no

The CAS Registry Mumber 1658-56-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1658-56:
(6*1)+(5*6)+(4*5)+(3*8)+(2*5)+(1*6)=96
96 % 10 = 6
So 1658-56-6 is a valid CAS Registry Number.
