922142-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 922142-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,2,1,4 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 922142-33:
(8*9)+(7*2)+(6*2)+(5*1)+(4*4)+(3*2)+(2*3)+(1*3)=134
134 % 10 = 4
So 922142-33-4 is a valid CAS Registry Number.
