1240385-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240385-90-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,3,8 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1240385-90:
(9*1)+(8*2)+(7*4)+(6*0)+(5*3)+(4*8)+(3*5)+(2*9)+(1*0)=133
133 % 10 = 3
So 1240385-90-3 is a valid CAS Registry Number.
