6739-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6739-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6739-21:
(6*6)+(5*7)+(4*3)+(3*9)+(2*2)+(1*1)=115
115 % 10 = 5
So 6739-21-5 is a valid CAS Registry Number.
