Check Digit Verification of cas no

The CAS Registry Mumber 21345-01-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,4 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21345-01:
(7*2)+(6*1)+(5*3)+(4*4)+(3*5)+(2*0)+(1*1)=67
67 % 10 = 7
So 21345-01-7 is a valid CAS Registry Number.
