Check Digit Verification of cas no

The CAS Registry Mumber 20357-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20357-20:
(7*2)+(6*0)+(5*3)+(4*5)+(3*7)+(2*2)+(1*0)=74
74 % 10 = 4
So 20357-20-4 is a valid CAS Registry Number.
