Check Digit Verification of cas no
The CAS Registry Mumber 6371-18-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6371-18:
(6*6)+(5*3)+(4*7)+(3*1)+(2*1)+(1*8)=92
92 % 10 = 2
So 6371-18-2 is a valid CAS Registry Number.
