68835-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68835-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,3 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68835-20:
(7*6)+(6*8)+(5*8)+(4*3)+(3*5)+(2*2)+(1*0)=161
161 % 10 = 1
So 68835-20-1 is a valid CAS Registry Number.
