1243531-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243531-85-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,5,3 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1243531-85:
(9*1)+(8*2)+(7*4)+(6*3)+(5*5)+(4*3)+(3*1)+(2*8)+(1*5)=132
132 % 10 = 2
So 1243531-85-2 is a valid CAS Registry Number.
