1258786-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258786-34-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,7,8 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1258786-34:
(9*1)+(8*2)+(7*5)+(6*8)+(5*7)+(4*8)+(3*6)+(2*3)+(1*4)=203
203 % 10 = 3
So 1258786-34-3 is a valid CAS Registry Number.
