Check Digit Verification of cas no

The CAS Registry Mumber 850404-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,4,0 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 850404-77:
(8*8)+(7*5)+(6*0)+(5*4)+(4*0)+(3*4)+(2*7)+(1*7)=152
152 % 10 = 2
So 850404-77-2 is a valid CAS Registry Number.
