156335-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156335-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,3 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156335-58:
(8*1)+(7*5)+(6*6)+(5*3)+(4*3)+(3*5)+(2*5)+(1*8)=139
139 % 10 = 9
So 156335-58-9 is a valid CAS Registry Number.
