40287-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40287-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,8 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40287-79:
(7*4)+(6*0)+(5*2)+(4*8)+(3*7)+(2*7)+(1*9)=114
114 % 10 = 4
So 40287-79-4 is a valid CAS Registry Number.
