1153665-58-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1153665-58-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,3,6,6 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1153665-58:
(9*1)+(8*1)+(7*5)+(6*3)+(5*6)+(4*6)+(3*5)+(2*5)+(1*8)=157
157 % 10 = 7
So 1153665-58-7 is a valid CAS Registry Number.
