Check Digit Verification of cas no

The CAS Registry Mumber 49770-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,7 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 49770-08:
(7*4)+(6*9)+(5*7)+(4*7)+(3*0)+(2*0)+(1*8)=153
153 % 10 = 3
So 49770-08-3 is a valid CAS Registry Number.
