40188-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40188-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,8 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40188-21:
(7*4)+(6*0)+(5*1)+(4*8)+(3*8)+(2*2)+(1*1)=94
94 % 10 = 4
So 40188-21-4 is a valid CAS Registry Number.
