Check Digit Verification of cas no
The CAS Registry Mumber 3442-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3442-21:
(6*3)+(5*4)+(4*4)+(3*2)+(2*2)+(1*1)=65
65 % 10 = 5
So 3442-21-5 is a valid CAS Registry Number.
