Check Digit Verification of cas no
The CAS Registry Mumber 1644-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1644-21:
(6*1)+(5*6)+(4*4)+(3*4)+(2*2)+(1*1)=69
69 % 10 = 9
So 1644-21-9 is a valid CAS Registry Number.
