Check Digit Verification of cas no

The CAS Registry Mumber 334994-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,9,9 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 334994-41:
(8*3)+(7*3)+(6*4)+(5*9)+(4*9)+(3*4)+(2*4)+(1*1)=171
171 % 10 = 1
So 334994-41-1 is a valid CAS Registry Number.
