219721-35-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219721-35-4 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 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219721-35:
(8*2)+(7*1)+(6*9)+(5*7)+(4*2)+(3*1)+(2*3)+(1*5)=134
134 % 10 = 4
So 219721-35-4 is a valid CAS Registry Number.
