Check Digit Verification of cas no
The CAS Registry Mumber 640721-49-9 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 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 640721-49:
(8*6)+(7*4)+(6*0)+(5*7)+(4*2)+(3*1)+(2*4)+(1*9)=139
139 % 10 = 9
So 640721-49-9 is a valid CAS Registry Number.
