205746-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205746-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,7,4 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 205746-41:
(8*2)+(7*0)+(6*5)+(5*7)+(4*4)+(3*6)+(2*4)+(1*1)=124
124 % 10 = 4
So 205746-41-4 is a valid CAS Registry Number.
