117151-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117151-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,5 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117151-62:
(8*1)+(7*1)+(6*7)+(5*1)+(4*5)+(3*1)+(2*6)+(1*2)=99
99 % 10 = 9
So 117151-62-9 is a valid CAS Registry Number.
