356093-54-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 356093-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,6,0,9 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 356093-54:
(8*3)+(7*5)+(6*6)+(5*0)+(4*9)+(3*3)+(2*5)+(1*4)=154
154 % 10 = 4
So 356093-54-4 is a valid CAS Registry Number.
