6864-21-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6864-21-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,6 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6864-21:
(6*6)+(5*8)+(4*6)+(3*4)+(2*2)+(1*1)=117
117 % 10 = 7
So 6864-21-7 is a valid CAS Registry Number.
