42818-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42818-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,1 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42818-91:
(7*4)+(6*2)+(5*8)+(4*1)+(3*8)+(2*9)+(1*1)=127
127 % 10 = 7
So 42818-91-7 is a valid CAS Registry Number.
