Check Digit Verification of cas no

The CAS Registry Mumber 221545-37-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,5,4 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221545-37:
(8*2)+(7*2)+(6*1)+(5*5)+(4*4)+(3*5)+(2*3)+(1*7)=105
105 % 10 = 5
So 221545-37-5 is a valid CAS Registry Number.
