Check Digit Verification of cas no
The CAS Registry Mumber 4756-09-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,5 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4756-09:
(6*4)+(5*7)+(4*5)+(3*6)+(2*0)+(1*9)=106
106 % 10 = 6
So 4756-09-6 is a valid CAS Registry Number.
