1357308-77-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1357308-77-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,3,0 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1357308-77:
(9*1)+(8*3)+(7*5)+(6*7)+(5*3)+(4*0)+(3*8)+(2*7)+(1*7)=170
170 % 10 = 0
So 1357308-77-0 is a valid CAS Registry Number.
