216864-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216864-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,8,6 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 216864-20:
(8*2)+(7*1)+(6*6)+(5*8)+(4*6)+(3*4)+(2*2)+(1*0)=139
139 % 10 = 9
So 216864-20-9 is a valid CAS Registry Number.
