Check Digit Verification of cas no

The CAS Registry Mumber 650-19-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 650-19:
(5*6)+(4*5)+(3*0)+(2*1)+(1*9)=61
61 % 10 = 1
So 650-19-1 is a valid CAS Registry Number.
