Check Digit Verification of cas no

The CAS Registry Mumber 211566-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,5,6 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 211566-89:
(8*2)+(7*1)+(6*1)+(5*5)+(4*6)+(3*6)+(2*8)+(1*9)=121
121 % 10 = 1
So 211566-89-1 is a valid CAS Registry Number.
