154276-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154276-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,2,7 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154276-93:
(8*1)+(7*5)+(6*4)+(5*2)+(4*7)+(3*6)+(2*9)+(1*3)=144
144 % 10 = 4
So 154276-93-4 is a valid CAS Registry Number.
