Check Digit Verification of cas no

The CAS Registry Mumber 100937-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,3 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 100937-72:
(8*1)+(7*0)+(6*0)+(5*9)+(4*3)+(3*7)+(2*7)+(1*2)=102
102 % 10 = 2
So 100937-72-2 is a valid CAS Registry Number.
