152386-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152386-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,3,8 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 152386-91:
(8*1)+(7*5)+(6*2)+(5*3)+(4*8)+(3*6)+(2*9)+(1*1)=139
139 % 10 = 9
So 152386-91-9 is a valid CAS Registry Number.
