Check Digit Verification of cas no

The CAS Registry Mumber 19782-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,8 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19782-68:
(7*1)+(6*9)+(5*7)+(4*8)+(3*2)+(2*6)+(1*8)=154
154 % 10 = 4
So 19782-68-4 is a valid CAS Registry Number.
