20656-67-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20656-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,5 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.Calculate Digit Verification of CAS Registry Number 20656-67:
(7*2)+(6*0)+(5*6)+(4*5)+(3*6)+(2*6)+(1*7)=101
101 % 10 = 1
So 20656-67-1 is a valid CAS Registry Number.
