90047-27-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90047-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,4 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90047-27:
(7*9)+(6*0)+(5*0)+(4*4)+(3*7)+(2*2)+(1*7)=111
111 % 10 = 1
So 90047-27-1 is a valid CAS Registry Number.
