123217-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123217-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,1 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123217-57:
(8*1)+(7*2)+(6*3)+(5*2)+(4*1)+(3*7)+(2*5)+(1*7)=92
92 % 10 = 2
So 123217-57-2 is a valid CAS Registry Number.
