1309868-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309868-22-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1309868-22:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*6)+(3*8)+(2*2)+(1*2)=181
181 % 10 = 1
So 1309868-22-1 is a valid CAS Registry Number.
