Check Digit Verification of cas no
The CAS Registry Mumber 140373-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,3,7 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140373-62:
(8*1)+(7*4)+(6*0)+(5*3)+(4*7)+(3*3)+(2*6)+(1*2)=102
102 % 10 = 2
So 140373-62-2 is a valid CAS Registry Number.
