Check Digit Verification of cas no

The CAS Registry Mumber 1256643-38-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,6,4 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1256643-38:
(9*1)+(8*2)+(7*5)+(6*6)+(5*6)+(4*4)+(3*3)+(2*3)+(1*8)=165
165 % 10 = 5
So 1256643-38-5 is a valid CAS Registry Number.
