Check Digit Verification of cas no

The CAS Registry Mumber 214610-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,6,1 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 214610-12:
(8*2)+(7*1)+(6*4)+(5*6)+(4*1)+(3*0)+(2*1)+(1*2)=85
85 % 10 = 5
So 214610-12-5 is a valid CAS Registry Number.
