Check Digit Verification of cas no

The CAS Registry Mumber 277755-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,7,7,5 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 277755-64:
(8*2)+(7*7)+(6*7)+(5*7)+(4*5)+(3*5)+(2*6)+(1*4)=193
193 % 10 = 3
So 277755-64-3 is a valid CAS Registry Number.
