Check Digit Verification of cas no

The CAS Registry Mumber 2850-27-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,5 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2850-27:
(6*2)+(5*8)+(4*5)+(3*0)+(2*2)+(1*7)=83
83 % 10 = 3
So 2850-27-3 is a valid CAS Registry Number.
