957799-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 957799-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,7,9 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 957799-30:
(8*9)+(7*5)+(6*7)+(5*7)+(4*9)+(3*9)+(2*3)+(1*0)=253
253 % 10 = 3
So 957799-30-3 is a valid CAS Registry Number.
