1058653-84-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1058653-84-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,8,6,5 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1058653-84:
(9*1)+(8*0)+(7*5)+(6*8)+(5*6)+(4*5)+(3*3)+(2*8)+(1*4)=171
171 % 10 = 1
So 1058653-84-1 is a valid CAS Registry Number.
