949155-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 949155-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,1,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 949155-91:
(8*9)+(7*4)+(6*9)+(5*1)+(4*5)+(3*5)+(2*9)+(1*1)=213
213 % 10 = 3
So 949155-91-3 is a valid CAS Registry Number.
