68950-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68950-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,5 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68950-21:
(7*6)+(6*8)+(5*9)+(4*5)+(3*0)+(2*2)+(1*1)=160
160 % 10 = 0
So 68950-21-0 is a valid CAS Registry Number.
