117370-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117370-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,3,7 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117370-44:
(8*1)+(7*1)+(6*7)+(5*3)+(4*7)+(3*0)+(2*4)+(1*4)=112
112 % 10 = 2
So 117370-44-2 is a valid CAS Registry Number.
