94235-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94235-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,3 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94235-83:
(7*9)+(6*4)+(5*2)+(4*3)+(3*5)+(2*8)+(1*3)=143
143 % 10 = 3
So 94235-83-3 is a valid CAS Registry Number.
