640722-49-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 640722-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,7,2 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 640722-49:
(8*6)+(7*4)+(6*0)+(5*7)+(4*2)+(3*2)+(2*4)+(1*9)=142
142 % 10 = 2
So 640722-49-2 is a valid CAS Registry Number.
