345958-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 345958-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,9,5 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 345958-79:
(8*3)+(7*4)+(6*5)+(5*9)+(4*5)+(3*8)+(2*7)+(1*9)=194
194 % 10 = 4
So 345958-79-4 is a valid CAS Registry Number.
