Check Digit Verification of cas no

The CAS Registry Mumber 67978-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,7 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67978-34:
(7*6)+(6*7)+(5*9)+(4*7)+(3*8)+(2*3)+(1*4)=191
191 % 10 = 1
So 67978-34-1 is a valid CAS Registry Number.
