957020-91-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 957020-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,0,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 957020-91:
(8*9)+(7*5)+(6*7)+(5*0)+(4*2)+(3*0)+(2*9)+(1*1)=176
176 % 10 = 6
So 957020-91-6 is a valid CAS Registry Number.
