Check Digit Verification of cas no

The CAS Registry Mumber 156979-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,9,7 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156979-39:
(8*1)+(7*5)+(6*6)+(5*9)+(4*7)+(3*9)+(2*3)+(1*9)=194
194 % 10 = 4
So 156979-39-4 is a valid CAS Registry Number.
