1219090-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1219090-51-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,0,9 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1219090-51:
(9*1)+(8*2)+(7*1)+(6*9)+(5*0)+(4*9)+(3*0)+(2*5)+(1*1)=133
133 % 10 = 3
So 1219090-51-3 is a valid CAS Registry Number.
