1236508-09-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1236508-09-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,5,0 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1236508-09:
(9*1)+(8*2)+(7*3)+(6*6)+(5*5)+(4*0)+(3*8)+(2*0)+(1*9)=140
140 % 10 = 0
So 1236508-09-0 is a valid CAS Registry Number.
