1210920-47-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1210920-47-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,9,2 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1210920-47:
(9*1)+(8*2)+(7*1)+(6*0)+(5*9)+(4*2)+(3*0)+(2*4)+(1*7)=100
100 % 10 = 0
So 1210920-47-0 is a valid CAS Registry Number.
