40691-62-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40691-62-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,9 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40691-62:
(7*4)+(6*0)+(5*6)+(4*9)+(3*1)+(2*6)+(1*2)=111
111 % 10 = 1
So 40691-62-1 is a valid CAS Registry Number.
