1355252-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1355252-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,5,2,5 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1355252-40:
(9*1)+(8*3)+(7*5)+(6*5)+(5*2)+(4*5)+(3*2)+(2*4)+(1*0)=142
142 % 10 = 2
So 1355252-40-2 is a valid CAS Registry Number.
