Check Digit Verification of cas no
The CAS Registry Mumber 2309-94-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,0 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2309-94:
(6*2)+(5*3)+(4*0)+(3*9)+(2*9)+(1*4)=76
76 % 10 = 6
So 2309-94-6 is a valid CAS Registry Number.
