118353-68-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118353-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,5 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118353-68:
(8*1)+(7*1)+(6*8)+(5*3)+(4*5)+(3*3)+(2*6)+(1*8)=127
127 % 10 = 7
So 118353-68-7 is a valid CAS Registry Number.
