640281-41-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 640281-41-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,8 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 640281-41:
(8*6)+(7*4)+(6*0)+(5*2)+(4*8)+(3*1)+(2*4)+(1*1)=130
130 % 10 = 0
So 640281-41-0 is a valid CAS Registry Number.
