1023971-87-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023971-87-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,9,7 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1023971-87:
(9*1)+(8*0)+(7*2)+(6*3)+(5*9)+(4*7)+(3*1)+(2*8)+(1*7)=140
140 % 10 = 0
So 1023971-87-0 is a valid CAS Registry Number.
