Check Digit Verification of cas no

The CAS Registry Mumber 1189377-98-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,3,7 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1189377-98:
(9*1)+(8*1)+(7*8)+(6*9)+(5*3)+(4*7)+(3*7)+(2*9)+(1*8)=217
217 % 10 = 7
So 1189377-98-7 is a valid CAS Registry Number.
