1233359-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1233359-56-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,3,5 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1233359-56:
(9*1)+(8*2)+(7*3)+(6*3)+(5*3)+(4*5)+(3*9)+(2*5)+(1*6)=142
142 % 10 = 2
So 1233359-56-2 is a valid CAS Registry Number.
