1423730-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1423730-33-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,3,7,3 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1423730-33:
(9*1)+(8*4)+(7*2)+(6*3)+(5*7)+(4*3)+(3*0)+(2*3)+(1*3)=129
129 % 10 = 9
So 1423730-33-9 is a valid CAS Registry Number.
