117934-94-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117934-94-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,3 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117934-94:
(8*1)+(7*1)+(6*7)+(5*9)+(4*3)+(3*4)+(2*9)+(1*4)=148
148 % 10 = 8
So 117934-94-8 is a valid CAS Registry Number.
