Check Digit Verification of cas no

The CAS Registry Mumber 1947-59-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,4 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1947-59:
(6*1)+(5*9)+(4*4)+(3*7)+(2*5)+(1*9)=107
107 % 10 = 7
So 1947-59-7 is a valid CAS Registry Number.
