40534-62-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40534-62-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,3 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40534-62:
(7*4)+(6*0)+(5*5)+(4*3)+(3*4)+(2*6)+(1*2)=91
91 % 10 = 1
So 40534-62-1 is a valid CAS Registry Number.
