Check Digit Verification of cas no

The CAS Registry Mumber 683775-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,3,7,7 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 683775-38:
(8*6)+(7*8)+(6*3)+(5*7)+(4*7)+(3*5)+(2*3)+(1*8)=214
214 % 10 = 4
So 683775-38-4 is a valid CAS Registry Number.
