Check Digit Verification of cas no

The CAS Registry Mumber 690996-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,9,9 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 690996-23:
(8*6)+(7*9)+(6*0)+(5*9)+(4*9)+(3*6)+(2*2)+(1*3)=217
217 % 10 = 7
So 690996-23-7 is a valid CAS Registry Number.
