Check Digit Verification of cas no

The CAS Registry Mumber 2951-54-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2951-54:
(6*2)+(5*9)+(4*5)+(3*1)+(2*5)+(1*4)=94
94 % 10 = 4
So 2951-54-4 is a valid CAS Registry Number.
