1243201-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243201-33-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,2,0 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1243201-33:
(9*1)+(8*2)+(7*4)+(6*3)+(5*2)+(4*0)+(3*1)+(2*3)+(1*3)=93
93 % 10 = 3
So 1243201-33-3 is a valid CAS Registry Number.
