145236-55-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145236-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,3 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 145236-55:
(8*1)+(7*4)+(6*5)+(5*2)+(4*3)+(3*6)+(2*5)+(1*5)=121
121 % 10 = 1
So 145236-55-1 is a valid CAS Registry Number.
