Check Digit Verification of cas no
The CAS Registry Mumber 143326-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,2 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143326-52:
(8*1)+(7*4)+(6*3)+(5*3)+(4*2)+(3*6)+(2*5)+(1*2)=107
107 % 10 = 7
So 143326-52-7 is a valid CAS Registry Number.
