1454615-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1454615-92-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,4,6,1 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1454615-92:
(9*1)+(8*4)+(7*5)+(6*4)+(5*6)+(4*1)+(3*5)+(2*9)+(1*2)=169
169 % 10 = 9
So 1454615-92-9 is a valid CAS Registry Number.
