1430236-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1430236-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,0,2,3 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1430236-99:
(9*1)+(8*4)+(7*3)+(6*0)+(5*2)+(4*3)+(3*6)+(2*9)+(1*9)=129
129 % 10 = 9
So 1430236-99-9 is a valid CAS Registry Number.
