219926-17-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219926-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,2 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 219926-17:
(8*2)+(7*1)+(6*9)+(5*9)+(4*2)+(3*6)+(2*1)+(1*7)=157
157 % 10 = 7
So 219926-17-7 is a valid CAS Registry Number.
