Check Digit Verification of cas no

The CAS Registry Mumber 60749-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,7,4 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 60749-72:
(7*6)+(6*0)+(5*7)+(4*4)+(3*9)+(2*7)+(1*2)=136
136 % 10 = 6
So 60749-72-6 is a valid CAS Registry Number.
