Check Digit Verification of cas no

The CAS Registry Mumber 143947-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,4 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143947-56:
(8*1)+(7*4)+(6*3)+(5*9)+(4*4)+(3*7)+(2*5)+(1*6)=152
152 % 10 = 2
So 143947-56-2 is a valid CAS Registry Number.
