Check Digit Verification of cas no

The CAS Registry Mumber 1420002-97-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,0,0 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1420002-97:
(9*1)+(8*4)+(7*2)+(6*0)+(5*0)+(4*0)+(3*2)+(2*9)+(1*7)=86
86 % 10 = 6
So 1420002-97-6 is a valid CAS Registry Number.
