117736-94-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117736-94-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,3 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117736-94:
(8*1)+(7*1)+(6*7)+(5*7)+(4*3)+(3*6)+(2*9)+(1*4)=144
144 % 10 = 4
So 117736-94-4 is a valid CAS Registry Number.
