1229227-17-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1229227-17-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,2,2 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1229227-17:
(9*1)+(8*2)+(7*2)+(6*9)+(5*2)+(4*2)+(3*7)+(2*1)+(1*7)=141
141 % 10 = 1
So 1229227-17-1 is a valid CAS Registry Number.
