Check Digit Verification of cas no
The CAS Registry Mumber 842-15-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 842-15:
(5*8)+(4*4)+(3*2)+(2*1)+(1*5)=69
69 % 10 = 9
So 842-15-9 is a valid CAS Registry Number.
