223932-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223932-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,9,3 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 223932-56:
(8*2)+(7*2)+(6*3)+(5*9)+(4*3)+(3*2)+(2*5)+(1*6)=127
127 % 10 = 7
So 223932-56-7 is a valid CAS Registry Number.
