Check Digit Verification of cas no

The CAS Registry Mumber 537658-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,7,6,5 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 537658-39:
(8*5)+(7*3)+(6*7)+(5*6)+(4*5)+(3*8)+(2*3)+(1*9)=192
192 % 10 = 2
So 537658-39-2 is a valid CAS Registry Number.
