1373331-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1373331-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,3,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1373331-52:
(9*1)+(8*3)+(7*7)+(6*3)+(5*3)+(4*3)+(3*1)+(2*5)+(1*2)=142
142 % 10 = 2
So 1373331-52-2 is a valid CAS Registry Number.
