647-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 647-40-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 647-40:
(5*6)+(4*4)+(3*7)+(2*4)+(1*0)=75
75 % 10 = 5
So 647-40-5 is a valid CAS Registry Number.
