1215112-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1215112-55-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,1,1 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1215112-55:
(9*1)+(8*2)+(7*1)+(6*5)+(5*1)+(4*1)+(3*2)+(2*5)+(1*5)=92
92 % 10 = 2
So 1215112-55-2 is a valid CAS Registry Number.
