1338382-30-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338382-30-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,3,8 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1338382-30:
(9*1)+(8*3)+(7*3)+(6*8)+(5*3)+(4*8)+(3*2)+(2*3)+(1*0)=161
161 % 10 = 1
So 1338382-30-1 is a valid CAS Registry Number.

, p. 9411 - 9416 (2011)
Diastereoselective introduction of phosphono groups into l-proline derivatives at the 5-position was achieved with suitable selection of N-protecting group. N-Benzoyl-l-prolinate preferentially gave trans-phosphorylated products, which could be easily tra
