1225202-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1225202-33-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,5,2,0 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1225202-33:
(9*1)+(8*2)+(7*2)+(6*5)+(5*2)+(4*0)+(3*2)+(2*3)+(1*3)=94
94 % 10 = 4
So 1225202-33-4 is a valid CAS Registry Number.
