1240787-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240787-44-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,7,8 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1240787-44:
(9*1)+(8*2)+(7*4)+(6*0)+(5*7)+(4*8)+(3*7)+(2*4)+(1*4)=153
153 % 10 = 3
So 1240787-44-3 is a valid CAS Registry Number.
