Check Digit Verification of cas no

The CAS Registry Mumber 1383950-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,9,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1383950-52:
(9*1)+(8*3)+(7*8)+(6*3)+(5*9)+(4*5)+(3*0)+(2*5)+(1*2)=184
184 % 10 = 4
So 1383950-52-4 is a valid CAS Registry Number.
