117927-09-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117927-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,2 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117927-09:
(8*1)+(7*1)+(6*7)+(5*9)+(4*2)+(3*7)+(2*0)+(1*9)=140
140 % 10 = 0
So 117927-09-0 is a valid CAS Registry Number.
