1403356-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1403356-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,3,5 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1403356-52:
(9*1)+(8*4)+(7*0)+(6*3)+(5*3)+(4*5)+(3*6)+(2*5)+(1*2)=124
124 % 10 = 4
So 1403356-52-4 is a valid CAS Registry Number.
