Check Digit Verification of cas no

The CAS Registry Mumber 217977-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,9,7 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 217977-63:
(8*2)+(7*1)+(6*7)+(5*9)+(4*7)+(3*7)+(2*6)+(1*3)=174
174 % 10 = 4
So 217977-63-4 is a valid CAS Registry Number.
