1338235-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338235-53-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,2,3 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1338235-53:
(9*1)+(8*3)+(7*3)+(6*8)+(5*2)+(4*3)+(3*5)+(2*5)+(1*3)=152
152 % 10 = 2
So 1338235-53-2 is a valid CAS Registry Number.
