40508-01-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40508-01-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,0 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40508-01:
(7*4)+(6*0)+(5*5)+(4*0)+(3*8)+(2*0)+(1*1)=78
78 % 10 = 8
So 40508-01-8 is a valid CAS Registry Number.
