344442-83-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344442-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,4,4 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 344442-83:
(8*3)+(7*4)+(6*4)+(5*4)+(4*4)+(3*2)+(2*8)+(1*3)=137
137 % 10 = 7
So 344442-83-7 is a valid CAS Registry Number.
