22156-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22156-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,5 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22156-55:
(7*2)+(6*2)+(5*1)+(4*5)+(3*6)+(2*5)+(1*5)=84
84 % 10 = 4
So 22156-55-4 is a valid CAS Registry Number.
