Check Digit Verification of cas no

The CAS Registry Mumber 6757-89-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,5 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6757-89:
(6*6)+(5*7)+(4*5)+(3*7)+(2*8)+(1*9)=137
137 % 10 = 7
So 6757-89-7 is a valid CAS Registry Number.
