Check Digit Verification of cas no

The CAS Registry Mumber 959907-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,9,9,0 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 959907-81:
(8*9)+(7*5)+(6*9)+(5*9)+(4*0)+(3*7)+(2*8)+(1*1)=244
244 % 10 = 4
So 959907-81-4 is a valid CAS Registry Number.
