Check Digit Verification of cas no

The CAS Registry Mumber 1238-47-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1238-47:
(6*1)+(5*2)+(4*3)+(3*8)+(2*4)+(1*7)=67
67 % 10 = 7
So 1238-47-7 is a valid CAS Registry Number.
