Check Digit Verification of cas no

The CAS Registry Mumber 19407-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,0 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19407-50:
(7*1)+(6*9)+(5*4)+(4*0)+(3*7)+(2*5)+(1*0)=112
112 % 10 = 2
So 19407-50-2 is a valid CAS Registry Number.
