Check Digit Verification of cas no

The CAS Registry Mumber 190662-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,6,6 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 190662-30:
(8*1)+(7*9)+(6*0)+(5*6)+(4*6)+(3*2)+(2*3)+(1*0)=137
137 % 10 = 7
So 190662-30-7 is a valid CAS Registry Number.
