157736-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157736-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,3 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 157736-63:
(8*1)+(7*5)+(6*7)+(5*7)+(4*3)+(3*6)+(2*6)+(1*3)=165
165 % 10 = 5
So 157736-63-5 is a valid CAS Registry Number.
