Check Digit Verification of cas no
The CAS Registry Mumber 6426-67-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6426-67:
(6*6)+(5*4)+(4*2)+(3*6)+(2*6)+(1*7)=101
101 % 10 = 1
So 6426-67-1 is a valid CAS Registry Number.
