Check Digit Verification of cas no

The CAS Registry Mumber 137527-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,2 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137527-23:
(8*1)+(7*3)+(6*7)+(5*5)+(4*2)+(3*7)+(2*2)+(1*3)=132
132 % 10 = 2
So 137527-23-2 is a valid CAS Registry Number.
