1309875-77-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309875-77-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,7 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1309875-77:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*7)+(3*5)+(2*7)+(1*7)=191
191 % 10 = 1
So 1309875-77-1 is a valid CAS Registry Number.
