1023548-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023548-58-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,5,4 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1023548-58:
(9*1)+(8*0)+(7*2)+(6*3)+(5*5)+(4*4)+(3*8)+(2*5)+(1*8)=124
124 % 10 = 4
So 1023548-58-4 is a valid CAS Registry Number.
