Check Digit Verification of cas no
The CAS Registry Mumber 103729-43-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,2 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103729-43:
(8*1)+(7*0)+(6*3)+(5*7)+(4*2)+(3*9)+(2*4)+(1*3)=107
107 % 10 = 7
So 103729-43-7 is a valid CAS Registry Number.
