234448-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 234448-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,4,4,4 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 234448-56:
(8*2)+(7*3)+(6*4)+(5*4)+(4*4)+(3*8)+(2*5)+(1*6)=137
137 % 10 = 7
So 234448-56-7 is a valid CAS Registry Number.
