243455-68-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 243455-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,4,5 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 243455-68:
(8*2)+(7*4)+(6*3)+(5*4)+(4*5)+(3*5)+(2*6)+(1*8)=137
137 % 10 = 7
So 243455-68-7 is a valid CAS Registry Number.
