1054640-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1054640-92-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,4,6,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1054640-92:
(9*1)+(8*0)+(7*5)+(6*4)+(5*6)+(4*4)+(3*0)+(2*9)+(1*2)=134
134 % 10 = 4
So 1054640-92-4 is a valid CAS Registry Number.
