201284-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 201284-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,2,8 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201284-79:
(8*2)+(7*0)+(6*1)+(5*2)+(4*8)+(3*4)+(2*7)+(1*9)=99
99 % 10 = 9
So 201284-79-9 is a valid CAS Registry Number.
