1140833-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1140833-77-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,0,8,3 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1140833-77:
(9*1)+(8*1)+(7*4)+(6*0)+(5*8)+(4*3)+(3*3)+(2*7)+(1*7)=127
127 % 10 = 7
So 1140833-77-7 is a valid CAS Registry Number.
