219724-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219724-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,2 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219724-35:
(8*2)+(7*1)+(6*9)+(5*7)+(4*2)+(3*4)+(2*3)+(1*5)=143
143 % 10 = 3
So 219724-35-3 is a valid CAS Registry Number.
