Check Digit Verification of cas no

The CAS Registry Mumber 6357-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6357-78:
(6*6)+(5*3)+(4*5)+(3*7)+(2*7)+(1*8)=114
114 % 10 = 4
So 6357-78-4 is a valid CAS Registry Number.
