943148-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 943148-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,1,4 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 943148-64:
(8*9)+(7*4)+(6*3)+(5*1)+(4*4)+(3*8)+(2*6)+(1*4)=179
179 % 10 = 9
So 943148-64-9 is a valid CAS Registry Number.
