Check Digit Verification of cas no

The CAS Registry Mumber 855658-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,6,5 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 855658-67:
(8*8)+(7*5)+(6*5)+(5*6)+(4*5)+(3*8)+(2*6)+(1*7)=222
222 % 10 = 2
So 855658-67-2 is a valid CAS Registry Number.
