1023287-49-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023287-49-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,2,8 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1023287-49:
(9*1)+(8*0)+(7*2)+(6*3)+(5*2)+(4*8)+(3*7)+(2*4)+(1*9)=121
121 % 10 = 1
So 1023287-49-1 is a valid CAS Registry Number.
