337356-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 337356-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,3,5 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 337356-25:
(8*3)+(7*3)+(6*7)+(5*3)+(4*5)+(3*6)+(2*2)+(1*5)=149
149 % 10 = 9
So 337356-25-9 is a valid CAS Registry Number.
