Check Digit Verification of cas no

The CAS Registry Mumber 1290137-43-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,1,3 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1290137-43:
(9*1)+(8*2)+(7*9)+(6*0)+(5*1)+(4*3)+(3*7)+(2*4)+(1*3)=137
137 % 10 = 7
So 1290137-43-7 is a valid CAS Registry Number.
