1234210-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1234210-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,2,1 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1234210-47:
(9*1)+(8*2)+(7*3)+(6*4)+(5*2)+(4*1)+(3*0)+(2*4)+(1*7)=99
99 % 10 = 9
So 1234210-47-9 is a valid CAS Registry Number.
