1308655-59-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1308655-59-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,8,6,5 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1308655-59:
(9*1)+(8*3)+(7*0)+(6*8)+(5*6)+(4*5)+(3*5)+(2*5)+(1*9)=165
165 % 10 = 5
So 1308655-59-5 is a valid CAS Registry Number.
