1233349-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1233349-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,3,4 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1233349-85:
(9*1)+(8*2)+(7*3)+(6*3)+(5*3)+(4*4)+(3*9)+(2*8)+(1*5)=143
143 % 10 = 3
So 1233349-85-3 is a valid CAS Registry Number.
