402718-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 402718-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,7,1 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 402718-76:
(8*4)+(7*0)+(6*2)+(5*7)+(4*1)+(3*8)+(2*7)+(1*6)=127
127 % 10 = 7
So 402718-76-7 is a valid CAS Registry Number.
