Check Digit Verification of cas no

The CAS Registry Mumber 2920-37-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2920-37:
(6*2)+(5*9)+(4*2)+(3*0)+(2*3)+(1*7)=78
78 % 10 = 8
So 2920-37-8 is a valid CAS Registry Number.
