1243249-08-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243249-08-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,2,4 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1243249-08:
(9*1)+(8*2)+(7*4)+(6*3)+(5*2)+(4*4)+(3*9)+(2*0)+(1*8)=132
132 % 10 = 2
So 1243249-08-2 is a valid CAS Registry Number.
