Check Digit Verification of cas no

The CAS Registry Mumber 127658-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127658-20:
(8*1)+(7*2)+(6*7)+(5*6)+(4*5)+(3*8)+(2*2)+(1*0)=142
142 % 10 = 2
So 127658-20-2 is a valid CAS Registry Number.
