Check Digit Verification of cas no

The CAS Registry Mumber 211757-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,7,5 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 211757-98:
(8*2)+(7*1)+(6*1)+(5*7)+(4*5)+(3*7)+(2*9)+(1*8)=131
131 % 10 = 1
So 211757-98-1 is a valid CAS Registry Number.
