1049013-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1049013-76-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,0,1 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1049013-76:
(9*1)+(8*0)+(7*4)+(6*9)+(5*0)+(4*1)+(3*3)+(2*7)+(1*6)=124
124 % 10 = 4
So 1049013-76-4 is a valid CAS Registry Number.
