Check Digit Verification of cas no
The CAS Registry Mumber 7657-09-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,5 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7657-09:
(6*7)+(5*6)+(4*5)+(3*7)+(2*0)+(1*9)=122
122 % 10 = 2
So 7657-09-2 is a valid CAS Registry Number.
