Check Digit Verification of cas no

The CAS Registry Mumber 137779-95-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,7 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137779-95:
(8*1)+(7*3)+(6*7)+(5*7)+(4*7)+(3*9)+(2*9)+(1*5)=184
184 % 10 = 4
So 137779-95-4 is a valid CAS Registry Number.
