Check Digit Verification of cas no

The CAS Registry Mumber 256643-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,6,4 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 256643-34:
(8*2)+(7*5)+(6*6)+(5*6)+(4*4)+(3*3)+(2*3)+(1*4)=152
152 % 10 = 2
So 256643-34-2 is a valid CAS Registry Number.
