Check Digit Verification of cas no
The CAS Registry Mumber 6642-10-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,4 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6642-10:
(6*6)+(5*6)+(4*4)+(3*2)+(2*1)+(1*0)=90
90 % 10 = 0
So 6642-10-0 is a valid CAS Registry Number.
