5Check Digit Verification of cas no
The CAS Registry Mumber 6470-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.Calculate Digit Verification of CAS Registry Number 6470-23:
(6*6)+(5*4)+(4*7)+(3*0)+(2*2)+(1*3)=91
91 % 10 = 1
So 6470-23-1 is a valid CAS Registry Number.
