Check Digit Verification of cas no
The CAS Registry Mumber 4321-69-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,2 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4321-69:
(6*4)+(5*3)+(4*2)+(3*1)+(2*6)+(1*9)=71
71 % 10 = 1
So 4321-69-1 is a valid CAS Registry Number.
