Check Digit Verification of cas no
The CAS Registry Mumber 23647-14-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,4 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23647-14:
(7*2)+(6*3)+(5*6)+(4*4)+(3*7)+(2*1)+(1*4)=105
105 % 10 = 5
So 23647-14-5 is a valid CAS Registry Number.
