Check Digit Verification of cas no

The CAS Registry Mumber 127016-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,1 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127016-40:
(8*1)+(7*2)+(6*7)+(5*0)+(4*1)+(3*6)+(2*4)+(1*0)=94
94 % 10 = 4
So 127016-40-4 is a valid CAS Registry Number.
