Check Digit Verification of cas no

The CAS Registry Mumber 344569-10-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,5,6 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 344569-10:
(8*3)+(7*4)+(6*4)+(5*5)+(4*6)+(3*9)+(2*1)+(1*0)=154
154 % 10 = 4
So 344569-10-4 is a valid CAS Registry Number.
