94941-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94941-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,9,4 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94941-23:
(7*9)+(6*4)+(5*9)+(4*4)+(3*1)+(2*2)+(1*3)=158
158 % 10 = 8
So 94941-23-8 is a valid CAS Registry Number.
